[PKG SUPPORT] changes for support of flake >=6.0.0 (and Python 3.12, implicit)

[valeriupredoi]

Hi @carlio et al (the good Prospector folk), here's your (annoying) friendly pkg maintainer - in order for Prospector to be built with Python 3.12, there are three direct dependencies that need to change lower and upper pin bounds (well, upper bound is not 100% needed, but safe):

- mccabe >=0.7.0,<0.8.0
- pycodestyle >=2.11.0,<2.12.0
- pyflakes >=3.1.0,<3.2.0

these are unfortunately dictated by flake8 >=6. Are these possible at the moment? If so, I can fire up a rebuild, and (AFAIK) even with a pylint=2.17.7 we can get us a python 3.12 supported build, so the issue of supporting pylint >=3 is not that pressing, Python 3.12-wise. Cheers muchly! 🍺

Hey, thank you for the investigation :) Feel free to open a merge request as most of the work is done. pylint 2.17.7 works with python 3.12 as long as you don't use 3.12 specific structure, but we do need pylint > 3 in the general case.

cheers muchly, mate! Will open a PR on the feedstock and one here (upstream), and let you guys accept the changes upstream at your own pace - am annoying enough about the pkg build 😁 🍺

I have opened #645 for upstream deps and a DNMY PR at the feedstock conda-forge/prospector-feedstock#44 that should wait for the upstream one - in the meantime I've realized that flake8>=6 will mean loss of support for Python 3.7 which is up to you guys to decide if can be done or not. At any rate, let me know if I can do anything else, and have a good weekend in the meantime 🍺

Looks to be fixed :-)
