rag_api documentation is worthless

[jamesyc]

RAG api setup doc: https://www.librechat.ai/docs/configuration/rag_api

Add the following to your .env file:

RAG_API_URL=http://host.docker.internal:8000

The problem is, port 8000 isn't exposed on the host side.

See the docker ps output:

This entire page of documentation for rag_api is absolutely worthless since the environment: section in the docker compose file overrides env_file and thus adding the RAG_API_URL line to .env is useless. You can set RAG_API_URL to "Librechat documentation sucks" and it will happily accept that variable and continue to ignore it.
