Support flake8==7.0.0

[jonyscathe]

flake8 7 is out so pyproject.toml should probably change from
"flake8 >= 6.0.0, < 7.0.0",
to
"flake8 >= 6.0.0, < 8.0.0",

as the breaking changes in flake8==7.0.0 are pretty minor.

I would also consider removing the upper bound as well. Flake8 breaking changes are often pretty minor and often don't break anything to do with extensions. And each time there is a new flake8 version, it takes weeks for all the extensions to update their upper bounds for flake8.

Thanks for opening the issue! Yeah, I agree that upper bounds (like the one we have!) are in general bad and make things more painful for users -- sorry about that. Unfortunately, we've been pretty badly broken before by flake8 refactoring their internals (see #257). This is entirely our fault rather than flake8's -- we monkey-patch some flake8 internals in an unauthorised way -- but at the same time, it's hard to see how we could stop doing that monkeypatching while keeping our full feature set. So, unfortunately, I think we need to keep the upper bound here.

@jonyscathe, the fix is included in flake8-pyi==24.1.0, which I just released: https://pypi.org/project/flake8-pyi/24.1.0/

Thanks for the quick fix. And understand not wanting to un-pin the upper bound if you are monkey patching
