Problem/Motivation
After a media image is translated to another language (by adding a translation to the alternative text of the image)
When adding a media image to a node, using the media library, it shows double content, instead of only 1 image.
This was already reported by @webchick, in #2954378: Use Media images in Umami demo
Proposed resolution
Display a single content per language, which is similar behavior to how adding a media image without media library currently works.
