fix: guard setAccessible() call for PHP 8.5+

ReflectionProperty::setAccessible() is deprecated in PHP 8.5 and will be
removed in PHP 9.0. Since PHP 8.1, all properties are accessible via
Reflection by default, making this call unnecessary.

This adds a version guard to only call setAccessible() on PHP < 8.5,
matching the pattern used in Laravel Telescope and Horizon.
