Enable Pyrefly in fbcode/vision/fair

Summary:
Automated migration to enable Pyrefly type checking for `fbcode/vision/fair`.

- Added `python.set_pyrefly(True)` to PACKAGE file
- Suppressed pre-existing type errors

Pyrefly is Meta's next-generation Python type checker, replacing Pyre.

If you encounter issues, you can revert the PACKAGE change by removing
the `python.set_pyrefly(True)` line.
