Product variation not translated on "add to cart" form

Even if the product variation is translated, the "add to cart" is not translated in the product variation label.
Here is code that i added, please create patch for this.

Drupal\commerce_cart\Form\AddToCartForm;
function public function submitForm ....
after $purchased_entity = $order_item->getPurchasedEntity();

$language = \Drupal::languageManager()->getCurrentLanguage(LanguageInterface::TYPE_INTERFACE)->getId();
    if($purchased_entity->hasTranslation($language)){
      $purchased_entity = $purchased_entity->getTranslation($language);
    }
