[ChatLSE] Update the `rag_advanced.py` file from the GraphRAG branch so it is line with the version of the develop

[jonjoncardoso]

Due date 30/Oct/2024

• Focus on the PostgreSQL (first) > Neo4J (later) solution
• Make sure that retrieval and generation works.
• Experiment with questions from the general benchmarking spreadsheet (+ use your creativity)
• Write up in the comments: what's good about it, what's not so good.

The GraphRAG branch is issue99/aksh-investigate-graph-database-3

Suggestion of merge (good luck with the merge conflicts):

git checkout issue99/kristina-experiment-graphrag-redesign
git checkout -b <your new branch name>
git merge <aksh's latest branch> --no-ff --no-commit
