Revert "[Github] Make PR formatting job only run with C/C++ changes (#69556)"

This reverts commit 80b2aac2c6.

I mistakenly assumed this job didn't also do python formatting
(should've grepped for more than just black in the python portion of
this script). Pulling it out for now to get python formatting working
again while the patch is iterated further.
