Incorrect typing for autoretry_for

[sk-]

We have the following code

@shared_task(
    autoretry_for=(PoolTimeout, CancelledError),
    max_retries=10,
    retry_backoff=True,
    retry_backoff_max=100,
    retry_jitter=False,
)
def my_task(...):
  ...

But unfortunately mypy it's throwing the following error:

error: Argument "autoretry_for" to "shared_task" has incompatible type "Tuple[Type[PoolTimeout], Type[CancelledError]]"; expected "Tuple[Type[Exception], ...]"  [arg-type]

The reason for this is that CancelledError extends from BaseException instead of Exception. This is the issue where they changed the base class.
