Keyboard layout list not translatable

In the “Welcome to Tails!” dialog when i select language like “Dansk (Danish)” the list under keyboard layout is in english:

<code class="text">
Danish
    Danish
    Danish (Dvorak)
    Danish (eliminate dead keys)
    Danish (Macintosh)
    Danish (Macintosh, eliminate dead keys)
    Danish (Winkeys)
</code>

I would like this list to be translatable so i can have it in danish.

Hopefully the list is already translated else where.

Tails 3.12.
