PHP 8.4.1 Compatibility issue.

Deprecated: Spatie\EloquentSortable\SortableTrait::setNewOrder(): Implicitly marking parameter $primaryKeyColumn as nullable is deprecated, the explicit nullable type must be used instead in /var/www/html/vendor/spatie/eloquent-sortable/src/SortableTrait.php on line 44

The code should be like this, enabling the null attribute type not to use implicitly marking the parameter's value as null:

public static function setNewOrder(
        $ids,
        int $startOrder = 1,
        string|null $primaryKeyColumn = null,
        callable|null $modifyQuery = null
    ): void {
...
}

We'd accept a PR that fixes this.
