Add support comments in JSON request body #599

[FreeBono]

PR Description

When a body in JSON format is provided, the function checks whether the body is in JSON format. If it is, the function returns the JSON string with comments removed. If not, it returns the input string as it is.

I have written test cases for removing single-line comments, multi-line comments, and other scenarios.

Thank you for the great feedback. I’ve modified the code in the core package to only remove comments when the data is in JSON format, ensuring that the existing data in the editor remains unchanged and comments are removed only during the send request
