Update isort version in pre-commit config

[aganders3]

The previous version was failing to install due to some issues with poetry. See PyCQA/isort#2078.

Then again, now that napari is using ruff for this, perhaps that should be used in the plugin cookiecutter as well.

I'm not sure as ruff is really fast in development and adding new rules.

I'm not against but it will require to preciselly preselect enabled rules and revisit it time to time.

Thanks for the input. I can see it both ways. On one hand pre-commit is basically pinning a version, so the fast changes shouldn't be a problem. On the other, I think we can expect many to use pre-commit autoupdate.

at this moment, I prefer to switch to ruff with removing flake and isort. It provides a much better user experience.

Sounds good - I will close this then!
