MacOS / ARM / "is not a supported wheel" error unless launching from Py 3.8.

Description

cibuildwheel.__version__ == '2.8.0'

When running cibuildwheel on Apple Silicon, I found that I need to run from a Python 3.8 interpreter.

Otherwise I encouter an issue where the wheel is built, but it can't be imported (I guess):

...
pip install /private/var/folders/...path/to/...-cp38-cp38-macosx_11_0_arm64.whl
ERROR: ....whl is not a supported wheel on this platform.

Workaround:

/Library/Frameworks/Python.framework/Versions/3.8/bin/python3 -m cibuildwheel --platform macos --archs arm64

There are some awkward details around Python 3.8 wheels on AS. We've changed the behaviour recently, though that's as-yet unreleased. It's not clear to me what exactly is failing for you here, but it might be fixed on main. Let me know if not.
