[flake8-pyi]: More autofixes for redundant-none-literal (PYI061)

[kiran-4444]

Summary

This PR solves #14537. I've tested it, and it's working as expected. I'll be updating this with tests tomorrow. The implementation isn't yet sanitised and can be refactored further. Any feedback in doing this is greatly appreciated.

Test Plan

Tested locally, will update the tests.

Thanks! A couple of issues here, but this broadly looks like it's on the right track :-)

Thanks @kiran-4444, this is a fantastic improvement! I pushed a couple of small changes:

• We can't safely offer the fix with the | syntax on Python <=3.9, as the | syntax for unions was added in Python 3.10. Possibly we could in the future use typing.Union for the fix and offer it even on older versions of Python, but I think we can leave that to another PR :-)
• I simplified the code slightly by combining the two create_fix_edit() functions
