Fix errors when a plural translation is missing (#1716)

## Description
Previously not every plural translation had full coverage and some did
not have the fallback "other" quantity translation. So for some
languages this would cause an error when trying to display the string
depending on the quantity. This PR ensures every plural translation has
the "other" fallback.

Note: the "other" fallback is copied from an existing translation so I'm
sure some will not be grammatically correct!

Dev note: I used a python script to parse and fix the entries, so it
also rewrote some of the unrelated `CDATA` entries.

### Related issues
Fixes #1676

### Testing
On the emulator, I reproduced the error in the issue with the Danish
translation, verified it was fixed after the patch was applied
