Build (and tag) Images / build (push) Successful in 1m23s
fix: Builds images with kaniko
There are no Windows runners; build the images with kaniko in a container
on the `docker` runner, as on the link-updates branch, while keeping the
publishing restrictions:

- only pushes to refs/heads/main publish, as `latest` and `sha-<commit>`
- other refs build with --no-push under a ci-<commit> tag
- registry credentials are only passed to the build when publishing

The docker compose smoke test is dropped, as there is no Docker daemon
inside the kaniko container.

# Images are only published for pushes to the main branch. All other refs (branches,
# renovate branches, tags) are built, but never pushed, and do not get registry credentials.
#
# Note: a workflow run for a pushed ref uses the workflow file from that ref, so this
# condition alone does not stop someone with push access from publishing images. The
# registry credentials must additionally be restricted to the protected main branch.
