Missing Dependency langchain_ollama in rag-api-dev-lite

[sreevatsank1999]

Running latest rag_api docker

FROM ghcr.io/danny-avila/librechat-rag-api-dev-lite:latest

With the following .env file

#==================================================#
#                        RAG                       #
#==================================================#
# More info: https://www.librechat.ai/docs/configuration/rag_api

RAG_API_URL=http://127.0.0.1:8000
RAG_PORT=8000 
EMBEDDINGS_PROVIDER=ollama
OLLAMA_BASE_URL=http://xyz:11434
EMBEDDINGS_MODEL=nomic-embed-text

I get the following error:

Traceback (most recent call last):
  File "/app/main.py", line 46, in <module>
    from psql import PSQLDatabase, ensure_custom_id_index_on_embedding, pg_health_check
  File "/app/psql.py", line 3, in <module>
    from config import DSN, logger
  File "/app/config.py", line 252, in <module>
    embeddings = init_embeddings(EMBEDDINGS_PROVIDER, EMBEDDINGS_MODEL)
  File "/app/config.py", line 206, in init_embeddings
    from langchain_ollama import OllamaEmbeddings
ModuleNotFoundError: No module named 'langchain_ollama'

Possibly because of a missing dependency

Missing dependency of langchain-ollama=0.2.0 seems to be the reason. Thanks @sreevatsank1999 for pointing this out.

I added it to requirements.lite.txt #85
