v1.16.2

Fixed

• Fixed two bugs in shebang validation that would result in ModuleNotFoundError when running check-munki-pkgsinfo hook.

Removed

• Dropped Python 2 string instance validation. No further support will be provided for Python 2.

Changed

• Added PyUpgrade hook to this repo's own pre-commit linting, in order to ensure modern Python syntax.
• Don't specify "r" mode when using open(), as this is the default behavior.
