PR: Build arm64 versions of Spyder's standalone macOS application

[mrclary]

Description of Changes

Add arm64 to build matrix

• Update Python to 3.10.11 (arm64 builds not available for Python 3.9 from setup-python)
• Update DMG name to include Spyder version and architecture

Note that py2app 0.28.5, I believe, should have updated the black recipe and resolved #19743. However, there is still an issue; see ronaldoussoren/py2app#518. The kluges from #21629 are still required.

Fixes #20232

@mrclary, to fix the error on CIs you need to change the Python version in this line

spyder/.github/workflows/installer-macos.yml

Line 92 in a45cdf4

run: touch ${pythonLocation}/lib/python3.9/site-packages/black-23.12.0.dist-info/top_level.txt

to 3.10 and then you need to make the necessary adjustments to this line:

spyder/.github/workflows/installer-macos.yml

Line 108 in a45cdf4

run: cp -v ${pythonLocation}/lib/python3.9/site-packages/629853fdff261ed89b74__mypyc* ${DISTDIR}/Spyder.app/Contents/Resources/lib/python3.9/

by changing the Python version there too and the name of the file 629853fdff261ed89b74__mypyc, which is Python version dependent. For the latter part, you need to install Black in a Python 3.10 env and get it from it.

And please also revert the version change you just did to py2app because it's not necessary. I mean, I fought a lot in PR #21629 to make our Github workflow work with more recent versions of py2app but I was unable to.

Thanks for the heads up; I almost went down that rabbit hole 😁.

FYI, the glob pattern is identical for the Python 3.10.11 environment (629853fdff261ed89b74__mypyc.cpython-310-darwin.so), so no change was needed.

Thanks @mrclary!
