Add cython-lint to pre-commit checks.

[bdice]

Description

Adds cython-lint (https://github.com/MarcoGorelli/cython-lint) to the list of pre-commit checks. It is most similar to flake8 but with support for Cython syntax -- the rule set it enforces is fairly short, it mostly helps identify unused imports in Cython files.

@MarcoGorelli Thanks for your work on cython-lint! I opened this PR to add cython-lint to our pre-commit checks. Since this build passed CI, I think the potential bug we discussed in #11684 has been fixed!
