Use FindPython when it is more supported by scikit-build

[hmaarrfk]

When trying to ensure broader compatibility with different implementations of python, I think it is likely better to use FindPython which was introduced in 3.12.

That said, it isn't fully supported by scikit-build, and as such, it is likely better to contribute efforts there in order to minimize effort duplication.
