Include a note on setting up virtual environments in readme or notebooks

[jvalente-salemstate]

This is a relatively minority "issue" but thinking back to when I started learning python, virtual environments were still "new", it was not covered in most material. Over time I'd built up various quirks that venv would have avoided

Users who are interested in using the notebooks and aren't familiar deeply familiar with python may be able to follow along with the instructions but be unaware that activating a python virtual environment is a good approach to handling dependency issues that can arise when different versions are needed.

Including this somewhere could save a lot of headache and troubleshooting to fix whatever issues arise, while yielding a better user experience.

At least on this page it gives some nice detail: https://www.elastic.co/search-labs/tutorials/chatbot-tutorial/chatbot-rag-app/backend
