Show number of times a document/chunk was cited #485
Description
See title. Once #416 is merged, I think all of the data would already be there so it should just be a matter of showing it on the frontend.
Showing this data on the Chatbot Knowledge Base page and Chatbot Settings page beside each chunk/document would be sweet.
We could also make an Insight for it, showing "most cited documents" and/or "most cited chunks" (these insights could be moved to its own issue)
