Add wheel support for musllinux

[jimisola]

Resolves: #1216

1. Wheels workflow worked for just musllinux.

See: https://github.com/jimisola/pygit2/actions/runs/7480533793/job/20360154960#step:6:10758

I've turned all combinations back on again and the workflow is running now. It seems to take around 2h10 for it to complete so, I'll have to check it tomorrow:

2. Tests workflow fails for "[x86_64 (ubuntu-22.04, pypy3.9)]" (and have no idea why - I hope you do).

3. If the wheels workflow passes and you have a solution to the failed tests workflow then the following remains:

a. remove musl branchfrom wheels workflow:

  push:
    branches:
    - master
    - musl

b. squash commits upon merge

Update:

• wheel workflow works
• tests workflow fails for "[x86_64 (ubuntu-22.04, pypy3.9)]" (and have no idea why - I hope you do).

I've re-run an old job and it fails as well, https://github.com/libgit2/pygit2/actions/runs/7480816047

Apparently there's a change in Pypy 7.3.14 that is the source of this failure.
Since it's is unrelated to this PR it won't block it.

Just remove the commented out lines, remove the musl branch from wheels workflow, rebase and squash.
And I will merge it.

Fixed. Ready for merge.

For planning purposes, when do you think that there will be a new release with musllinux wheel support?

Thanks for a great project.

@jimisola Soon after CI is green again, but don't know when the Pypy error will be fixed.

Ok. Thanks. Is there an issue a pypy that one can follow?

[jdavid]

Apparently this has been fixed in latest version, PyPy v7.3.15

But the wheels now take a lot more time to build.
To reduce the time we can:

• Build only musl wheels for x86_64, not aarch64
• Build only musl wheels for latest versions of Python, 3.12 and 3.11

What do you actually need?

[jimisola]

Great. I think it's enough for us with what you've listed, but just let me double-check and get back to you.

And yes, I noticed that wheels take a lot longer. Is that an actual problem - built-time and/or CI/CD minutes?
I mean there might be other users that have other needs in terms of arch and python version.
It might not be obvious for them that they can ask for those to be turned on.

[jimisola]

@jdavid Let's go with your suggestion: x86_64 and Python, 3.12 and 3.11

[jimisola]

@jdavid Did you see this? Should improve execution time a bit.

[jdavid]

Release done. Finally I only dropped the wheels for aarch64, that's what takes most time.

[jimisola]

Great. Thanks for accepting the PR and the continued work with it.
