Update required for flake8 4.*

[Athanasius]

Flake8 4.x released recently, and after waiting for flake8-isort to update for it I'm now running into:

The conflict is caused by:
    The user requested flake8==4.0.1
    flake8-comprehensions 3.7.0 depends on flake8!=3.2.0, <5 and >=3.0
    flake8-docstrings 1.6.0 depends on flake8>=3
    flake8-isort 4.1.1 depends on flake8<5 and >=3.2.1
    flake8-noqa 1.2.0 depends on flake8<5.0 and >=3.8.0
    flake8-polyfill 1.0.2 depends on flake8
    flake8-use-fstring 1.1 depends on flake8==3.*

Only the last line appears to be an issue. Hopefully this is just a tweak to the version in requirements/installs, and no code changes will be needed.

Sorry I don't have the capacity to update this plugin right now. Everyone is welcome to make PRs and I will merge/publish as long as CI tests pass.
