Cleanup docker-compose.yaml versions in Noble services

On Ubuntu Noble we run `docker compose` instead of `docker-compose`.
This newer tool ignores the version set in docker-compose.yaml files and
emits a warning when it is set. Clean up this version on services that
only run with `docker compose` and not `docker-compose`.
