Replace broken chatbot with fixed link to endpoint (#1373)

Instead of rebuilding the chatbot to a static asset and integrating when
we need it, there's a new endpoint we can just link to directly.

The chatbot UI has updated somewhat to a full-screen (identical to the
chatbot here: https://docs.nvidia.com/)
