String freeze exception request for xdg-desktop-portal-kde 6.7

[David Redondo]

Hi everyone,

It's me again asking for a freeze exception, sorry for that! A misleading 
string has been found in xdg-desktop-portal-kde which would be fixed by 
https://invent.kde.org/plasma/xdg-desktop-portal-kde/-/merge_requests/564

The string has been already in 6.6 but I still wanted to ask if  we could 
backport a fix to 6.7, I thinking touching 6.6.6 is not worth it.

Cheers,
David
