Switch to the pre-commit mirror for black

This mirror was created to leverage performance optimizations from
mypyc wheels that are available if black is installed from PyPI. These
wheels are not available if black is installed from source as it would
be using the old URL. Please see psf/black#3828 and psf/black#3405 for
more information.
