improve QUEST documentation

[JessicaS11]

Looking through our docs page, it would be great to add some more QUEST documentation/clarity. Specific tasks/ideas:

• [x] Add uml generation for QUEST (via #498)
• [x] Clarify the QUEST-icepyx relationship in the API docs (perhaps giving QUEST its own API page?)
• [ ] Mention QUEST in the intro to icepyx docs (via #514)
• [ ] provide a detailed guide for adding a dataset via QUEST
• [ ] Add a tile for QUEST on the home page! (via #497)
• [x] Add a link to AGU presentation/JupyterBook (and mint DOI for presentation)

Going to start by working on the last checkbox - I think we discussed giving the Jupyterbook a Zenodo link.

Does icepyx have a Zenodo community ID? I could upload the notebook through my personal account, though it might be preferable to have a group Zenodo.
