No Windows free-threaded wheel available in scientific-python-nightly-wheels

In scikit-learn we noticed there are no Windows free-threaded development wheel in scientific-python-nightly-wheels.

The reason seems to be that your Wheels builder has failed consistently for more than a week, see build logs.

The failures only happen for Windows free-threaded i.e. cp313t-win_amd64. I had a quick look at one of the log there are almost 300 failures and plenty of them seem to be related to indexes with timestamps ...

One thing I did notice is that you are still using numpy development wheel for Windows free-threaded and I think using a released numpy may be good enough since numpy 2.2.4 (and probably a few earlier versions as well) has a free-threaded wheel for Windows, see PyPI numpy info.

Thanks for the ping. We've started an attempt to try to root cause these failures in #61240 but not much progress yet

In Arrow we have temporarily disabled testing with pandas for Windows free-threaded to unblock our 20.0.0 release. We will re-enable once this issue is fixed. Thanks!
