[BE] Update flake8-comprehensions to 3.11.1 (pytorch#97671)

Updates flake8-comprehensions in lintrunner so we can enforce new checks that have been implemented since the last update (including one implemented by me). I also added C417 to the flake8 ignore codes for now since we do not yet conform to that check.
