pyqt6-without-qt

I want to be able to run mypy on pre-commit.ci to type-check PyQt6 code. However, since Qt is so large, I'm getting the error

build of https://github.com/pre-commit/mirrors-mypy:pyqt6,...@v1.9.0
for python@python3 exceeds tier max size 250MiB: 277.2MiB

Since all I care about are the stubs, I simply modify the wheels to remove the dependency on PyQt6-Qt6. Now, upon replacing pyqt6 with pyqt6-without-qt in my additional_dependencies, I am under the quota and can run the full type checks.

(The particular project this is being used for is Labelle.)
