Add support for pyflakes 3.1

`ContinueInFinally` is dropped in pyflakes 3.1 [1].

flake8 is bumped to a version that supports pyflakes 3.1 [2].

pyflakes is also bumped to have the same version range as flake8 [2]
(thanks ccordoba12 for the notice).

Closes #412

[1] PyCQA/pyflakes#752
[2] https://flake8.pycqa.org/en/latest/release-notes/6.1.0.html
