CI Use released numpy for Windows wheels testing
Following #61249 this also used released numpy for testing on Windows free-threaded wheels.
I guess this doesn't fix the nightly wheels failure, since the issue seems related to cython dev according to https://github.com/pandas-dev/pandas/pull/61249.

It could still be worth to merge this PR to use released numpy.

I'll move it ouf of draft, when the wheels are back to green on `main`. OK I guess this is ready to be reviewed, this simplifies the Windows free-threaded further (on top of #61249) by using released numpy for testing. cc @mroeschke.

The Wheels testing seems to be fine, see [build log](https://github.com/pandas-dev/pandas/actions/runs/14374817755/job/40304732103?pr=61248).

Not quite sure why the mypy error is about since it does not seem related to my PR, see [build log](https://github.com/pandas-dev/pandas/actions/runs/14374817701/job/40304672507?pr=61248). Thanks @lesteve (and for your initial stab at debugging our wheel failures)
