Mohammad Mohtashim ae3551c96b core[patch]: Correct type casting of annotations in _infer_arg_descriptions (#31181)
- **Description:** 
- In _infer_arg_descriptions, the annotations dictionary contains string
representations of types instead of actual typing objects. This causes
_is_annotated_type to fail, preventing the correct description from
being generated.
- This is a simple fix using the get_type_hints method, which resolves
the annotations properly and is supported across all Python versions.

  - **Issue:** #31051
