STYLE: upgrade flake8

Issue here is:

1. checkout the create-pr-action/pre-commit-config-update-0 branch
2. run pre-commit run flake8 --all-files. You should see some errors like:

1. Fixup these errors, and when pre-commit run flake8 --all-files passes, stage, commit, and push!

Could we just ignore them for now, so we can get the upgraded versions, and have a todo or an issue about enabling them?

Yep that definitely makes more sense, thanks! I’ll try to get to this today.
