Ignore Python patch version for --universal pip compile (#14405)

## Summary

The idea here is that if a user runs `uv pip compile --universal`, we
should ignore the patch version on the current interpreter. I think this
makes sense... `--universal` tries to resolve for all future versions,
so it seems a bit odd that we'd start at the _current_ patch version.

Closes #14397.
