flake8 configuration is broken

[brianbeck-google]

Trying to run make lint in the software directory successfully runs isort and black but flake8 fails. That check should be fixed or disabled.

cd software
make venv  # TODO: further testing to understand if this is required on initial checkout
make setup
make lint

Expected: 3 tools run

Actual:

For anyone wondering what the exact change has been that fixed it and doesn't want to diff the OP's config against this new config like I did: rev: 3.9.2 of flake8 was changed to rev: 5.0.4 ;
