Add json_to_string usage example

[ZGT23]

Description

Splashkit Function: json_to_string

Overview of example functionality:
This pull request adds a beginner-friendly usage example for the json_to_string function in the Json category.

The example creates a Json object from a valid JSON string using json_from_string(), then converts the Json object back into a readable string using json_to_string(). The original JSON string and converted output are printed to the terminal so beginners can clearly see what the function returns.

This example helps users understand how SplashKit Json objects can be converted into text for display, debugging, or saving.

Approved. This is a clear and beginner-friendly usage example for json_to_string. The example demonstrates the function well by converting a Json object back into a readable string, and the output is easy for beginners to understand. The added C++, C#, Python, title, and screenshot files are consistent with the expected usage example format. Good work.

The code and example implementation look good overall and everything appears to be working correctly.
One thing still needed is registering the new usage example in scripts/json-files/usage-example-references.json so it can be properly referenced and displayed in the documentation site. Once thats sorted it should be ready to approve!
