I was able to work around the issue with google.iam.v1 import missing in virtualenv. To work around it, disable virtualenv usage in nox, and when testing, don't use venv.

python3 -m nox -s docfx --no-venv

This was able to generate the documentation. However, it's still empty - I checked the Sphinx HTML and it still only generated the following:

I'll close this as WAI. Looks like we'll need more content before we can start generating the files.
