feat: add json_rag.ipynb, update readme

[cormac-rynne]

Added a notebook to cover a simple technique to apply RAG with JSON data.

Implemented with SentenceTransformer and FAISS to simplify being able to run offline and without API keys.

Update README.md to include references

Hi, I'm trying to go over the new notebook, and i'm getting:

[cormac-rynne]

Heya, I think it was because I built it in colab originally then downloaded it. I copied and pasted into a normal notebook and it seems to have fixed the problem

[NirDiamant]

Thanks, I can now see it.
Several points to fix:

• Please try to break down the long cells into smaller, easy-to-understand cells.
• Elaborate more with each markdown on what is going to appear in that cell (give the user motivation and understanding in advance)
• Show the results of what we've done. I believe such a short JSON file will make less sense. Maybe load a bigger one and show the user a snippet of the first several elements.
• Explain it in a way that a junior developer without any prior understanding will be able to grasp it.

thanks!!

Show the results of what we've done

I noticed in the contribution file that you said not to include notebook outputs so I've not included these, but happy to include these if needed

[NirDiamant]

There should be a making sense balance. we don't want to show garbage, but if it is crucial for the tutorial we want to show it

[cormac-rynne]

For sure, makes sense. Included the outputs
