------------------
- Drop isort 4.x support.
[gforcada]
- Add support for flake8 6.0.0.
[gforcada]
- Add `--isort-no-skip-gitignore` option to allow temporarily overriding the set
value of isort's `skip_gitignore` option with `False`. This can cause
flake8-isort to run significantly faster at the cost of making flake8-isort's
behavior differ slightly from the behavior of `isort --check`. [gschaffner]
