Update client.nb_NO.yml

v1 Complete translation for client.nb_NO.yml

All strings now have a first-take translation. Might have missed some due to the inconsistent use of double quotes, single quotes and no quotes (we're still good!).

I'm not entirely sure what happens when I apply edits to a still pending-for-pull patch; sorry if I goofed.
