Weblate: Fix Guarani (Paraguay)

Hi Christian, Sophi

At your earliest convenience, can you fix the name of Guarani language
from "gug (generated) gug" to Guarani Paraguay

BTW, in Weblate github (*), I see Guarani as

gn;Guarani;2;n != 1

Thank you

Done.

gn;Guarani;2;n != 1

And is the plurals form correct? (is the same in pootle and is same in
weblate since it also is default...)

ciao
