Sort out Python wheel generation

[cschwan]

Something is wrong with the wheel generation in the release action:

• for MacOs Python 3.7, 3.8, 3.9 and 3.10 aren't generated
• wheels for Python 3.12 are generated although they aren't setup with the setup-python action. A possible explanation is that they are installed by default and maturin build --find-interpreter is too clever and finds them.

wheels for Python 3.12 are generated although they aren't setup with the setup-python action. A possible explanation is that they are installed by default and maturin build --find-interpreter is too clever and finds them.

I don't believe to be Maturin's fault (for py3.12), since if it is installed by default it might be impossible to distinguish from the one you requested to install (maturin build is not GitHub Worfklows-specific, so, if it finds the executable in $PATH, that's it - I guess...).
