Meta: Translate config and fields (i18n)

The field's description, menu actions, and everything else that is not user-generated should be translatable. For example, this field in Spanish should have a different label and description.

If ChatGPT got it right:

Label should be: Contenido relacionado
Description should be: Arrastra para reordenar los elementos de contenido.
