I was unable to make it work with bzlmod, here's a minimal repro: https://github.com/dizzy57/bazel_py_minimal

Also, CPython=={major}.{minor}.* should be the default constraint.

@mattem I have removed some unrelated diff from my failed attempt before using PEX. Now diff should be smaller and easier to understand.
