Fix type hints for unittest.util.unorderable_list_difference() (#11012)

Fix type hints for unorderable_list_difference()

It claimed that the arguments were `Sequence` types (immutable), but the function removes elements from them, so they must be `MutableSequence` types. Specifically, it calls `pop()` on the first argument and `remove()` on the second argument.

See the function implementation for details:
