Do not call Reflection*::setAccessible() in PHP >= 8.1

[W0rma]

As of PHP 8.1.0, calling this method has no effect; all methods are invokable by default.

(https://www.php.net/manual/en/reflectionmethod.setaccessible.php and https://www.php.net/manual/en/reflectionproperty.setaccessible.php).

There're even plans to deprecate the method in PHP 8.5: https://wiki.php.net/rfc/deprecations_php_8_5#extreflection_deprecations

Thanks for fixing this!

Thank you fixing it, would be great to create new release to prevent deprecation warnings for PHP 8.5 early adopters like Drupal

I created a tag, please let me know when you have any issues.

Thank you, new release allowed to pass unit tests for Drupal!
