Add new Russian translation for User Guide
Hello, my name is Julia Dronova, I'm the Russian Gnome Translators Team coordinator. We have a translated .po on l10n.gnome.org, I made a clone of the Gnumeric repo here but I couldn't figure out which directory in the tree should I commit to to make a subsequent merge request.
The translation link: https://l10n.gnome.org/media/upload/gnumeric-master-help-ru-986958.merged.po
Kindly somebody submit the file to the repo OR please explain where I have to commit to in the forked tree, whatever action would be the easiest. TY!
