RemoteImageFormatter uses title instead of alt

The RemoteImageFormatter uses the title instead of the alt field when rendering the remote image.

   public function viewElements(FieldItemListInterface $items, $langcode) {
     $elements = [];
 
     // Add one image per item.
     foreach ($items as $delta => $item) {
       ...
       // Set the alt field.
       if ($this->fieldDefinition->getSetting('alt_field') === 1) {
         $elements[$delta]['#alt'] = $item->title;
       }
     }
 
     return $elements;
   }
