`QueryFilter::make()` should return `static` instead of `self`

[kblais]

Static analysis throws an error with this code :

class JobFilter extends QueryFilter
{
    ...
}

class JobController
{
    protected JobFilter $filter;

    public function index(Request $request) {
        $this->jobFilter = JobFilter::make(['foo' => $request->input('foo')]);
    }
}

Error from PHPStan : "Property JobController::$filter (JobFilter) does not accept Kblais\QueryFilter\QueryFilter"
