bring docker spring (without mutagen) up to date
bring docker spring (without mutagen) up to date

the root docker-compose.spring.yml had drifted quite a bit from the
container configs. this could cause some strange side effects with
processes in the spring container seeing different files than the other
containers. but most obviously this was breaking spring in
docker-compose v2 because some of the volumes previously referenced here
didn't exist anymore.

now spring (without mutagen) works again \o/
