## Description

Sets the `CELERY_SKIP_CHECKS` value to a string value (`'true'`) instead of a Boolean. Updates the existing test to patch in this string value instead of `True`

An integration test that validates that command line argument handling in `celery/bin/celery.py` matches the unit test assumptions would be a nice addition. However, since it should test more than just this option, it is far enough afield that I have not added it.

Fixes #8461.
