Put long param sections in dropdowns

[JWCook]

In docs for functions with tons of request parameters (mostly the observation endpoints), these param lists take up most of the space in the doc page. Example: https://pyinaturalist.readthedocs.io/en/stable/modules/pyinaturalist.v1.observations.html

It would be nice to put these under dropdown boxes (collapsed by default). Since these param lists are generated by sphinx-autodoc and sphinx-autodoc-typehints, though, I'm not quite sure how to do that.
