Expand Windows shim detection to include python3.12.exe (#2209)

## Summary

Our Windows shim detection wasn't catching shims like `python3.12.exe`.

Closes #2208.

## Test Plan

Installed Python 3.12 via the Windows Store; verified that `cargo run
venv --python 3.12` failed before but passes after this change.
