WHL: upgrade cibuildwheel to 3.0.0 (OpenAstronomy/github-actions-workflows v2.0.0)

[neutrinoceros]

testing out OpenAstronomy/github-actions-workflows#278, and adjusting settings:
pypy builds are now disabled by default, and pp39 requires enable: pypy-eol, which I think is a sign that we should start building against more recent versions of pypy instead, though, for the time being, I'm doing a simple dependency upgrade with no observable change.

Looks like the wheel-building workflow was automatically disabled, which defeats the purpose of this PR.
Could @mhvk or @avalentino turn it back on ?

[mhvk]

@neutrinoceros - I'm trying to parse the workflows, but I actually do not understand why the wheel-building is not run, nor know how to enable it. Let me ping @astrofrog, who I think implemented it (and who certainly understands github actions better).

[neutrinoceros]

Nevermind, it seems to be activated already (thanks to @avalentino, I suppose !). Let me just power cycle this PR, and bump to beta2 while I'm at it.

[neutrinoceros]

This seems to be going well, so the upgrade should be trivial when the stable release is out.
What do you think about upgrading PyPy wheels to pp310 ? this version has been available for almost 2 years and doesn't seem about to get away anytime soon. I could do this in a separate PR.

[neutrinoceros]

undrafting now that cibuildwheel 3.0.0 is out
Ping @mhvk

[neutrinoceros]

Whoops, got a build error on windows and no time to fix it right now, sorry about the noise. I'll try to circle back to it later today !

[neutrinoceros]

Actually this failure is unrelated and reproduced in #170

[neutrinoceros]

Got it, the bug is in Python 3.13.4 itself, and fixed in 3.14.5, which should be available on GHA in a matter of minutes to hours:
xref python/cpython#135151
xref actions/python-versions#344

Thanks @neutrinoceros
