CI: Restore Postgres to services, use service name as hostname

Gitea runs jobs in containers, so service containers are networked by
name (same as GitHub Actions with container:). Postgres goes back into
services: and is addressed as 'postgres', not localhost. MinIO stays
as a manual docker run with --network container:$(hostname) since it
needs `server /data` and is addressed as localhost.
