Drop 3.13t support

[ngoldbaum]

What do these changes do?

See the note at https://cibuildwheel.pypa.io/en/stable/changelog/#v341 and pypa/cibuildwheel#2787.

The cpython-freethreading option will be removed in the next release of cibuildwheel.

I'm going through repositories on GitHub that enable this option and sending in PRs to disable it. Happy to answer questions about this. I also took the opportunity to drop 3.13t CI.

If you're curious why 3.13t support is going away so soon, see https://py-free-threading.github.io/ci/#building-free-threaded-wheels-with-cibuildwheel for further guidance.

Are there changes in behavior for the user?

The next release will not include cp313t wheel builds.

@ngoldbaum Glad to see you here, seems some other people might be busy so I'll help you with the reviewing process.

[Vizonex]

All of this looks good might need to add a comment or two about why 3.13t is being removed but other than that I approve of this pull request.

[Vizonex]

That should be good enough now.

Waiting for feedback about the changes I let everyone on the matrix know that a workflow was left hanging.

Apart from the change note, looks good. I'll wait for Nick and Sam to take a look before proceeding.

[webknjaz]

Could you symlink think to packaging? Also, I'm not sure if this counts as breaking.

cc @Dreamsorcerer @bdraco WDYT?

LGTM once other comments are addressed. clearly 3.13t was not ready for production use so removing wheels is reasonable

[ngoldbaum]

Sorry for taking two weeks to click the button! I think this is ready now.

Good because we were worried that you just left on an hiatus, if I don't see anything new needing to be changed I'll request for this PR to be merged.
