Subject: [ci skip] Need to mention debug_exception_response_format in the
 api_app documentation.

- #23771 removed the reference to debug_exception_response_format from the api_app documentation.
- We need to let users know, they have ability to configure debug_exception_response_format in their development environment.
- Added documentation for the same in api_app.md file
- Grammar corrections
