Updated to fix lint and indent, and also add the missing comment:

https://github.com/python/cpython/blob/3.14/Lib/random.py#L839-L843

This and the 3.14 backport are also missing the test from the original PR:

https://github.com/python/cpython/pull/149222/changes

I've added it here, and have opened another PR to add to 3.14: #154879.
