Phalcon\Mvc\Model::findFirst() Incorrect annotation return type

[s-ohnishi]

     * @return bool|\Phalcon\Mvc\ModelInterface
     */
    public static function findFirst($parameters = null)
    {
    }

I think it should be this.

     * @return null|\Phalcon\Mvc\ModelInterface
     */
    public static function findFirst($parameters = null)
    {
    }

because

public static function findFirst(
    mixed $parameters = null
): ModelInterface | null

and

NOTE: findFirst() no longer returns false if records were not found.
