Address docker compose issues (#232)

[nleroy917]

The documentation was out of date in particular to the docker compose deployment. Changes were made to remove any references to setup_db.sh streamline the postgres docker container in compose, and fix some dependency issues that were occurring with Docker and torch.

Noteworthy changes:

1. Create a new docker-specific reqs file (requirements-all-docker.txt).
2. Remove all instances of setup_db.sh in the docs.
3. Simpify the docker-compose.yaml file to no longer build a custom postgres instance
4. Add more docker compose documentation to discuss GitHub auth and Qdrant.
