The bezalel-vps-runner is registered in host mode (:host labels)
and cannot execute Docker containers. The container pinning added
in #180 causes all Gitea CI jobs to fail immediately with:
Cannot connect to the Docker daemon at unix:///var/run/docker.sock
Remove container: from .gitea/workflows/*.yml while keeping it in
.github/workflows/ for actual GitHub Actions runners.
Fixes CI for all open PRs and main branch pushes.
