Fix a false negative for ``unused-import`` (#7678)

* Fix a false negative for ``unused-import`` when a constant inside ``typing.Annotated`` was treated as a reference to an import.

* Update with Daniël's suggestions:

- More understandable function parameter name.
- Update function parameter type: Expect a tuple of strings.

Closes #7547
