As part of the support for categories (T188605), in addition to allow users to map and add categories it may be helpful to allow translators to check them.
Similar to the case of links, a card can be used to preview the selected category. The card will provide:
- The category name and allow to open the category page in a new tab by clicking on it.
- The category name for the source wiki, allowing to open it too.
- An option to remove the category, which is equivalent to removing the category with the "X" from the list of category tags.
