Consider adding an template for a tool node that implements RAG solution

[gplutov]

Hi,
First of all, I would like to say this repo is an amazing start kit for AI agents developers!
Something that I thought can be useful is to add also some example of a tool that uses RAG with a usage of some open source vector db - in example chroma DB or milvus.
What do you think about it?

Hey, thanks! I agree, this is a good idea. I’d welcome a PR.
