6890daa9 - community: make AthenaLoader profile_name optional and fix type hint (#24958)

community: make AthenaLoader profile_name optional and fix type hint (#24958) - **Description:** This PR makes the AthenaLoader profile_name optional and fixes the type hint which says the type is `str` but it should be `str` or `None` as None is handled in the loader init. This is a minor problem but it just confused me when I was using the Athena Loader to why we had to use a Profile, as I want that for local but not production. - **Issue:** #24957 - **Dependencies:** None.
