pre-push.sh: Use python3 if python is not found

xu-cheng · xu-cheng · commit 365d4f4fd0ca · 2022-04-11T12:02:40.000-07:00
Since Python 2 has reached EOL, `python` may not be available in certain
systems (e.g., recent macOS). We should use `python3` in this case to
avoid error like `python: No such file or directory`.
