Fix: format CAST as :: less aggressively

[georgesittas]

Fixes #2554

I went with the any approach instead of .. and not args.get("safe") to ensure we there are no future regressions if we were to add new args to Cast.

FYI this change was triggered due to a mypy error, probably caused by the latest Faker release.

I verified that the uuid is a string value, but I went ahead and used str here to enforce this instead of t.cast.

>>> import faker
>>> type(faker.Faker().uuid4())
<class 'str'>
