public-reverse-proxy(host): Increase nginx worker fd limit

By default the limit on file descriptors is at a 1024 hard limit and 520k hard limit.
Unsure how this affects nginx, but each client connection needs two file descriptors.
So let's try to set the limit of open files explicitly.

-# Matrix Moderation
-
-All Matrix rooms created around CCCHH and which are considered *official* are subject to centralized moderation.
-This moderation is enforced by a [Mjolnir](https://github.com/matrix-org/mjolnir) bot on a techincal level and operated by a dedicated sub-team of the Infra Group.
-
-The moderation team can be reached at [matrix-moderation@hamburg.ccc.de](mailto:matrix-moderation@hamburg.ccc.de).
-
-## Principles and Guidelines
-
-During moderation, we adhere to the following principles:
-
-- No *predictive policing*. We strive for fast and accurate moderation and, while we do incorporate reports from trustworthy sources close to the chaos community, we do not moderate based on gut feelings.
-
-- Prohibited content includes spam, pornography, harassment, and fascist-like behavior. We remove such content and subsequently ban the user responsible (see [Matrix: Taking Moderation Action](../guides/matrix-taking-moderation-action.md)).
-
-- The CCCHH admin account may be used under special circumstances to issue warnings and explain the moderation team’s decisions in general terms. It does not respond to DMs and does not engage in discussions. If moderation action is to be discussed, people are referred to the moderation team at [matrix-moderation@hamburg.ccc.de](mailto:matrix-moderation@hamburg.ccc.de) instead.
-
-- New Matrix rooms related to CCCHH are **always** created by the CCCHH admin and protected by the moderation bot. See [Matrix: Create a New Room](../guides/matrix-create-room.md) for details on creating rooms.
-
-## How It Works
-
-The bot account `@moderation:hamburg.ccc.de` (Draupnir) maintains various internal lists of rules that are applied in so-called "Protected Rooms".
-These can include, for example, user bans or entire server bans.
-Additionally, certain automatic monitoring measures (so-called "protections") apply in these rooms, which trigger a configured action if violated.
-For example, a user is not allowed to tag too many other users in a single message, as this is considered spam and results in a kick.
-The bot is controlled and configured via a privileged *CCCHH Moderation Management* room using `!mjolnir` commands.
-There, individual actions can also be triggered through the bot as needed, such as redacting messages, kicking users from all or some channels, etc.
-
-It is also possible to make our moderation bot's local lists available to other entities and subscribe our bot to other entities' lists.
-Our list is published in `#general-moderation:hamburg.ccc.de` where other moderation bots can freely watch it.

-# Matrix: Create a New Room
-
-!!! success "Goal"
-
-    Create a new matrix room for a CCCHH group or function with correct protections and permissions
-
-## 1. Create the Room
-
-Rooms are always created by the *CCCHH-Admin* Account whose credentials can be found in *infra-secrets*.
-To create a room, log in to https://element.hamburg.ccc.de and click on *New Conversation* -> *New Room*.
-Enter a Room Name and optionally give it an address on the *hamburg.ccc.de* server.
-
-## 2. Configure Room Metadata
-
-Once the room is created, please give it a topic and if possible a room icon.
-This makes it easier to distinguish the many rooms we have.
-
-## 3. Invite the Moderation-Bot
-
-Either perform the following steps via the GUI or enter the displayed commands into the chat window of the new room:
-
-
-1. Invite the User `@moderation:hamburg.ccc.de` to the new room
-   ```
-   /invite @moderation:hamburg.ccc.de
-   ```
-
-2. Give the moderation bot *Admin* Power-Level so that it can properly enforce all protections
-   ```
-   /op @moderation:hamburg.ccc.de 100
-   ```
-
-## 4. Set Up Room Protection
-
-We have now added the moderation bot to the room but this is not enough.
-The bot needs to be told explicitly which rooms it should protect and the newly created one therefore needs to be added to that list.
-
-First, note down the *Internal Room ID* which can be found in the new Rooms settings under the *Advanced* tab.
-Then enter the *CCCHH Moderation Management* room and write the following draupnir command while substituting the copied room id:
-
-```
-!draupnir rooms add <room-id>
-```
-
-## Closing Up
-
-You should now have a new Matrix Room under moderation protection.
-To verify that everything was done correctly, you can enter `!draupnir verify` in the *CCCHH Moderation Management* room and observe that the moderation bot does not give you an error.

-
-    Perform common moderation actions in Matrix using our moderation bot
-
-See the [Matrix-Moderation](../concepts-and-configurations/matrix-moderation.md) Concept for an overview on how the moderation system functions.
-
-All bot actions are triggered through the *CCCHH Moderation Management* room.
-
-!!! warning "Warning"
-
-    Moderation actions should be triggered through the bot to avoid exposing members of the moderation team to harassment.
-    Even if the bot is unwieldy, think before taking action with your personal account and do so on your own scrutiny.
-
-## Banning a User
-
-```
-!draupnir ban user general <glob> <reason>
-```
-
-- `<glob>` can be a user ID (e.g. `@example:matrix.org`) but also more sophisticated. Be careful when using actual glob syntax as whole servers can be banned even if just a single user is the intended target.
-- `<reason>` is technically optional but should always be supplied so that we know why a certain user was banned in retrospect. The bot supports parsing quotations so `"<reason>"` is usually what you want if more than one word is used.
-
-## Banning a Server
-
-```
-!draupnir ban server general <glob> <reason>
-```
-
-- `<glob>` can be used to ban subdomains of a domain too, e.g. `*.example.com`. If used, an additional `--force` is required after the whole command.
-- `<reason>` should be supplied and supports quotation (`"<reason>") if more than one word is used
-- When a domain is banned, we usually also ban all subdomains too. This needs to be done in two separate commands.
-
-## Redacting a single Message
-
-```
-!draupnir redact <permalink>
-```
-
-- `<permalink>` is **not** the message ID but the actual *https://matrix.to/#blablabla* link that can be retrieved with most clients through a *Share* or *Copy link to Message* button on an individual message.
-
-## Redacting all Messages of a User
-
-```
-!draupnir redact <user-id>
-```
-
-- `user-id` the Matrix-ID of the user of whom all messages in all rooms should be redacted (e.g. `@bla:example.com`).
