Incorrect callable function signatures

[ehsanmok]

Across the SDK in different places, the use of typing callable is wrong if it was meant to use Callable. For example, here predictor_cls signature is defined as callable[string, sagemaker.session.Session] and was used like this. If normal Callable was meant (which should be unless specified otherwise) then the last type is the returnType so it should be corrected as something like Callable[[string, sagemaker.session.Session], Any].

Hi @ehsanmok,

Thanks for submitting the issue. The signature is in docstrings and if you are interested in contributing to the repo, please feel free to do so.
