Remove restart config from docker-compose

[SandersAaronD]

This should fix some build problems we see where images persist after docker-compose is killed and has very little downside, if any.

I purged my containers/images/volumes and pulled down this branch and ran 'make docker' and got the same issue:

Attaching to ai-training-api-1, db-1, loki-1, mimir-1, pyroscope-1, tempo-1, grafana-with-training-app
Gracefully stopping... (press Ctrl+C again to force)
Error response from daemon: Ports are not available: exposing port TCP 0.0.0.0:4040 -> 0.0.0.0:0: listen tcp 0.0.0.0:4040: bind: address already in use
make: *** [docker] Error 1

I can progress past the issue by restarting the grafana-with-training-app and the pyroscope-1 containers. They start up fine when restarting them and then localhost works as expected.
