How to update virt-viewer translations

[Frediano Ziglio]

Hi,
  I'm trying to fix https://bugzilla.redhat.com/show_bug.cgi?id=1503187,
a translation bug in virt-viewer.
It's not clear how to proceed. Looking at virt-viewer source the translations
are synced from Zanata. I have an account on Zanata but the virt-viewer project
seems in a read-only state. How to update translations?

Regards,
  Frediano
