ShopPageHydrator ignores attribute translations

[mitelg]

Description:
ShopPage custom attributes are not properly hydrated by ShopPageHydrator
when requesting a shop page via the shopware_storefront.shop_page_service.
(more details below)

Possible solution:
engine/Shopware/Bundle/StoreFrontBundle/Gateway/DBAL/Hydrator/ShopPageHydrator.php:95 should pass the translationKey parameter: $this->attributeHydrator->addAttribute($shopPage, $data, 'pageAttribute', null, 'page');.

This is done in the ManufacturerHydrator.

Details:
I have added custom (translatable) attributes to s_cms_static_attributes. These attributes can be translated and saved within the backend. In a custom component I request
a page from shopware_storefront.shop_page_service via getList method.
When requesting the attribute via $page->getAttribute('core')['custom_attribute'] the attribute is always in the default language.

As far as I can tell, other hydrators are also affected.
