tools/models/scvi docs adjustments

[mlin]

A few minor updates to the scvi docs; mainly, I hit weird ImportErrors without using a clean virtualenv.

[ivirshup]

One minor comment, but generally looks good. Would like @ebezzi to take a look before merging though.

Any chance you have the traceback from those ImportErrors?

[mlin]

@ivirshup I found one in my notes, ImportError: cannot import name 'html5lib' from 'pip._vendor'. I presume it was something to do with using a different python version than shipped with ubuntu 20.04, but I didn't look too closely once I found it worked in the virtualenv.
