Closes #171

x-ref: wntrblm/nox#567

It's a suboptimal that they introduced behaviour difference between CI vs non-CI environments.

Agreed this is a better fix. Once this is merged I'll update #171 to just add 3.10 into CI. (And 3.11? I'm not sure how to spell "3.11rc1" for the github action and we'd have to change it once 3.11 final comes out, so maybe just wait till then)

I opened this Nox issue that would hopefully make allow restoring the original behaviour in the noxfile.py itself. Please comment if you think this might also help/be preferred in your use case. I often find myself using the same Nox defaults as the pip team.
