Fetch compose file from the git tag and use compose v2

- goauthentik.io/version/<x>/docker-compose.yml only exists for old releases; download lifecycle/container/compose.yml of the version tag instead and always store it as docker-compose.yml
- restart handler used the removed docker_compose (v1) module; switch to community.docker.docker_compose_v2
