ci: Add yesqa pre-commit hook

[matthewfeickert]

Description

Add yesqa pre-commit hook and use it to remove an unused noqa: F401 from

pyhf/src/pyhf/infer/__init__.py

Line 207 in 1494b66

from pyhf.infer import intervals # noqa: F401

As the use of the flake8 config options count and statistics in setup.cfg cause issues with yesqa (c.f. asottile/yesqa#132, PyCQA/flake8#1458) move them to the flake8 pre-commit hook as args. (Thanks @henryiii for the good suggestion.)
