Summary

This PR introduces a new setting, enable_extended_json_syntax, to control the activation of the extended JSON syntax.

Background:

Details:

• When enable_extended_json_syntax is set to true, the extended JSON syntax features are enabled.
• When enable_extended_json_syntax is set to false (default), the extended JSON syntax features are disabled, ensuring compatibility with previous versions.

• fixes: #[Link the issue here]
