GHA uses Python 3.9 for building docs, but Python 3.10 for building package

Python 3.9

Lines 21 to 24 in 5930933

Python 3.10

Commentary

I assume this was not intentional. I recommend using Python 3.10 for all three; or documenting why the docs-related ones are still using Python 3.9.

[eecavanna]

They each use a distinct version of the actions/setup-python action, too.
