chore: use 2x faster black mirror

Thanks @henryiii! Looks like the latest typeguard release requires a newer typing-extensions version that clashes with the requirements made by tensorflow (which caps the typing-extensions version). This conflict has unfortunately happened before, I'll have a look to fix this externally and can then rebase this for CI to pass.

I'd bring it up with the TF people, and maybe recommend they remove the cap on this. Very high chance it's actually fine (typing-extensions doesn't break stuff much, and is mostly useful at type-check time, not runtime), and they've loosed some other caps before.

Looks like this will be fixed in the next TF release: https://github.com/tensorflow/tensorflow/issues/60687#issuecomment-1655280362.

edit: target for that is Sep 6 according to https://discuss.tensorflow.org/t/upcoming-tensorflow-2-14-branch-cut-release-dates/18220

Will restrict typeguard temporarily to have working CI and then revert that after the next TF release. See #428.

* switch to faster black mirror for pre-commit
