Updated Azure doc ingestion example to include RAG chatbot

[devinbost]

I updated the Azure document ingestion example to now be fully LangChain compatible and demonstrate a RAG chatbot on the data ingested by the pipeline.

I don't understand the test failure output.

Found runtime impl changed after building, please build the runtime impl and commit the changes.

no changes added to commit (use "git add" and/or "git commit -a")

What does this mean?
