Updates to CI and fix tests

[naveen521kk]

• tests: fix test warning, use absolute path
• Don't use windows-2016 (it's nearing EOL) see #66
• Upgrade dependencies for the build
• Don't build subprojects manually on macOS build
• Add separate test workflow and not use docker in tests
• Only upload wheels if tests pass
• Include license files in all the wheels
• Link wheels statically on macOS

Do we have to do something about the failing build?

Ah, sorry I didn't mark it as a draft. It's still a WIP.

OK, fine. You actually seemed to even have requested a review :)

I guess that's because you are a Code owner here,

@PhilippImhof This PR is ready and waiting for your review :).

@PhilippImhof Thanks for the review. It would be nice if you could test the macOS wheels also https://github.com/ManimCommunity/ManimPango/suites/4557070397/artifacts/122415312

I currently have some environment problems on my machine and thus cannot properly test the macOS wheels. But I think we can go for it, no?

Yeah, I guess at least it works on Github's machine.

I'll do a release later today. I guess it should be a major bump right because of https://github.com/ManimCommunity/ManimPango/pull/65
