PR Summary

• Removed PHP Unit Watcher
  The unused .phpunit-watcher.yml file was deleted, streamlining the project structure.

• Updated Log for New Enhancement
  The CHANGELOG.md file was updated to showcase a significant new enhancement that includes support for symfony/console version ^7.0.

• Enhanced Dependencies in composer.json
  The composer.json file was revised to support symfony/console version ^7.0, thus bringing in the benefits of the latest Symfony features. Furthermore, the obsolete spatie/phpunit-watcher dependency was removed, boosting the overall project's performance.

• Optimized Import Statements
  The src/Command/Game.php and src/Command/Serve.php files now include the use Symfony\Component\Console\Attribute\AsCommand statement, ensuring that the necessary Symfony command attributes can be used directly.

• Refactored Game Command
  The src/Command/Game.php file's structure was refactored. Redundant $defaultName and $defaultDescription properties were removed and replaced by the #[AsCommand('|yii', 'A Guessing Game')] class annotation, thus improving code readability and maintainability.

• Refactored Serve Command
  Likewise, the src/Command/Serve.php file was updated. By replacing the $defaultName and $defaultDescription properties with the #[AsCommand('serve', 'Runs PHP built-in web server')] class annotation, the code structure is now more straightforward and easy to manage.

• Improved Testing Stub
  Changes were also made to the tests/Stub/ErrorCommand.php file. The $defaultName and $defaultDescription properties were discarded and replaced with the #[AsCommand('error', 'Error command tests')] class annotation, making the testing process significantly more accessible and efficient.
