CMakeLists.txt: fix find_package(Python ...)

- drop version string hack (no longer needed since switching to
  cibuildwheel)
- drop Interpreter component (was never needed)
- use more specific Development.Module component
- add REQUIRED option
- drop version requirement (scikit-build provides all needed info)

Requires recent scikit-build fix to properly find the library.
