[BUG]: Lib\\Models\\RobotError::findFirst(): Return value must be of type ?Phalcon\\Mvc\\ModelInterface, Phalcon\\Mvc\\Model\\Row returned

[kvityasya]

When overriding the findFirst method with columns I get an error:
"Lib\\Models\\RobotError::findFirst(): Return value must be of type ?Phalcon\\Mvc\\ModelInterface, Phalcon\\Mvc\\Model\\Row returned"

Steps to reproduce the behavior:

Model without redefining method findFirst

<?php

namespace Lib\Models;

use Phalcon\Mvc\Model;

class RobotCorrect extends Model
{
    public $id;
    public $title;
    public $deleted;
}

RobotCorrect::findFirst(['columns' => 'title']); 

// Result: correct behavior 

Model with redefining method findFirst

<?php

namespace Lib\Models;

use Phalcon\Mvc\Model;

class RobotError extends Model
{
    public $id;
    public $title;
    public $deleted;

    public static function findFirst($params = null): ?ModelInterface
    {
        return parent::findFirst($params);
    }
}

RobotError::findFirst(['columns' => 'title']);

// Result: error "Lib\\Models\\RobotError::findFirst(): Return value 
// must be of type ?Phalcon\\Mvc\\ModelInterface, Phalcon\\Mvc\\Model\\Row returned"

I also get this error using phalcon 4, Can we merge #15890 together into 4? For some reason, I was unable to upgrade to 5. Thanks for any answers. @niden
