feature: add manylinux_2_28 image

[mayeut]

fix #1282

Add manylinux_2_28 images based on AlmaLinux 8.
The following architectures are supported:

• x86_64
• aarch64
• ppc64le

s390x might be added later on depending on availability of a base image.
i686 won't be added.

Wheels built with this image for x86_64 are at https://github.com/mattip/numpy/actions/runs/1836100699. In the artifact section at the bottom, the cp3*-manylinux_x86_64.zip files each contain a wheel.

So all builds & tests seem to be ok !
I did not know NumPy was using cibuildwheel (although I guess just for testing, not for official wheels which still use multibuild ?)
I admit I was not too worried about numpy x86_64 as it's C only on the most tested architecture.
I added some alt-arch images (& moved the x86_64 one):

• quay.io/pypa/manylinux_2_28_poc_x86_64:poc
• quay.io/pypa/manylinux_2_28_poc_ppc64le:poc
• quay.io/pypa/manylinux_2_28_poc_aarch64:poc

I might be able to create a PR at https://github.com/MacPython/openblas-libs to see if alt-arch build properly with these images.

NumPy was using cibuildwheel

The goal is to move to cibuildwheel for the next release (in July), and to move SciPy to cibuildwheel too.

cool, that would be nice
