feat(users): Add get_serializer_class to FileUploadView

Introduced a `get_serializer_class` method in the `FileUploadView` class to avoid warnings about the missing `serializer_class` attribute. This change ensures better code clarity and suppresses unnecessary warning messages during runtime, without altering the dynamic serializer class resolution based on the `media_type` in the request data. This adjustment provides a cleaner, more maintainable codebase and enhances developer experience by clearly communicating the intentional dynamic behavior of serializer class selection.
