pickle dictionary when it isn't JSON serializable

[samhita-alla]

Tracking issue

Why are the changes needed?

This is useful for serializing dictionaries that aren't JSON serializable. To enable pickling the data, the dict type needs to be annotated with allow_pickle set to True:

@task
def t1() -> Annotated[dict, kwtypes(allow_pickle=True)]
    ...

Pickling only happens if the dict isn't JSON serializable.

What changes were proposed in this pull request?

Modify DictTransformer to add support for pickling dictionaries and include relevant test cases. I've also updated the BotoTask output type to allow pickling when the dict isn't JSON serializable.
