Failure is real, contourpy does not provide windows arm wheels on python 3.10.

As such, I think I lean towards not bothering to backport this... we were already kind of on the fence. I'd rather keep the versions of python we have in the 3.10 series and not add a new platform than either drop a python version or deal with complicating CI config...

Any objections to just not backporting? (@tacaswell @QuLogic in particular)

what does the patch to skip py310 on arm look like?

I think it would be adding the following line to the 3.10 step (this is a pared down version of the pypy condition which was edited already to exclude win-arm).

        if: matrix.os != 'windows-11-arm'

I have tried it, now to see if it works, if it does we can go forward with the backport, if not probably not worth further troubleshooting (barring simple things like yaml syntax errors).
