In PHP 8.1, >> non-final internal methods now require overriding methods to declare a compatible return type, otherwise a deprecated notice is emitted during inheritance validation.
RFC: https://wiki.php.net/rfc/internal_method_return_types
Because of this, we receive a deprecation notice when running our code with PHP8.1.
This PR adds #[ReturnTypeWillChange] attribute where it is needed, in order to avoid the described problem and keep backward compatibility.
