**Problem:**
Currently, it appears as if editors can add `mul` descriptions in the termbox. But when they try, they receive an error message, that says `mul` is not allowed for descriptions. We need to make this more intuitive.
**Notes:**
* The reason is that we only allow the language code `mul` for Labels and Aliases and not for descriptions (T313027).
**Solution:**
Remove descriptions for `mul` language code from the users' termbox workflow
**Mockups:**
**Acceptance criteria:**
[] When viewing an Item, the termbox shows "-" as a description for `mul` (see mockup).
[] When editing an Item, the termbox shows no edit field for descriptions for `mul` (see mockup).
