Pull request overview

This pull request removes the redundant ext-json dependency from all provider composer.json files across the repository. Since PHP 8.0, the JSON extension is always enabled and bundled with PHP core, making the explicit declaration unnecessary for packages requiring PHP ^8.0 or higher. This cleanup improves dependency accuracy and follows best practices for Composer dependency management.

Changes:

• Removed "ext-json": "*" from 236 provider composer.json files
• Removed "ext-json": "*" from the root composer.json file
• All affected files require PHP ^8.0 or higher (versions 8.0, 8.1, 8.2, 8.3, or 8.4)
