Add ChatGPT-Like Experience for the Dataiku Documentation Sites

It would be really awesome if we could have a chatbot that uses ChatGPT or similar large language model to help end users answer questions they have about DSS. It can be trained on the DSS docs.

From my understanding the open-source project langchain has a ReadtheDocs loader which is what Dataiku docs is using. I think this may be a quick win to add and it would enhance the experience for all Dataiku users!

Story Point:

As a Dataiku end user I want to have a chat-gpt like experience to help answer any questions I have about DSS from the documentation sites so that I can easily have my questions answered without searching too hard on the documentation sites.

Note: Perhaps this can later be built into the help tab directly inside of DSS.
