Proposed Behavior

Celery tasks created with @app.task should support typing.get_type_hints(my_celery_task).

It can be solved by copying the __annotations__ from the decorated function when available. This is done by functools.wraps() in Python 3.0+, if I understand PEP 3107 correctly. Without this typing.get_type_hints(my_celery_task) raises an exception.

It is my understanding that some other similar properties that functools.wraps handles are already copied:
