docker_compose(role): use community.docker.docker_compose_v2 module

Use the community.docker.docker_compose_v2 module as it supports proper
changed handling out of the box, making the roles code more
straightforward and work. Also just do a docker compose restart instead
of having the custom docker compose reload script.
