`@internal` annotation does not supress `public_member_api_docs` lint on functions

meta: 1.12.0

Currently, the @internal annotation does not suppress the public_member_api_docs on functions. This is inconsistent with the behaviour of @internal on classes and mixins.

Summary: The @internal annotation currently does not suppress the public_member_api_docs lint on functions, unlike its behavior on classes and mixins, leading to inconsistent lint behavior.
