Fix: monkey-patch gradio_client get_type for bool schema crash on Gradio 5.12.0

The same TypeError 'argument of type bool is not iterable' bug exists in
gradio_client/utils.py get_type() when schema is a boolean (e.g. from
additionalProperties: true in JSON schema). Patch get_type and
_json_schema_to_python_type to return 'Any' for non-dict schemas.
