ci: add 3.13 wheels

[henryiii]

Adding 3.13 (non-free-threaded at the moment).

  E       AssertionError: Regex pattern did not match.
  E        Regex: "Can't pickle"
  E        Input: "Can't get local object 'test_serialise_with_nonserialisable_attrs.<locals>.<lambda>'"

@henryiii "cp313", "cp313t" are now available and numpy is also (as of a few hours ago) producing 3.13t wheels as well. Worth another try now!

[henryiii]

Passing.

[lgray]

Guessing because of cramjam workaround we presently cannot test 3.13t?

[henryiii]

3.13 works with the workaround. Either cramjam happens to work with it or we don’t use enough of it to be affected by any breakage.

3.13t probably not.

[henryiii]

Ah, yes, you have the t.

[lgray]

Where do you see it in the tests? Or are you saying I'm asking for it and we don't have it? If the latter, I guess we just wait a bit for setup-python to make a release.

[henryiii]

We aren't building 3.13t yet in cibuildwheel, so it's not built or tested. I'm assuming there's no chance this workaround works on 3.13t; I'm not even sure PyO3 main supports 3.13t yet.

For PyO3 (current, not old version), see Quansight-Labs/free-threaded-compatibility#53.

All the tests that this PR branch runs are now required, and nothing that it doesn't run is required. Now I'll update and auto-merge.
