[Live-demo] Changed translation

[Astrid Emde]

Hello,

I change the wiki page

https://wiki.osgeo.org/wiki/Live_GIS_Translate

I replaced the svn commands with git commands. At the moment it was a  
bit confusing.

One command I did not replace yet:

svn copy doc/en/<doc>.rst doc/lang/<doc>.rst (old version with svn)

Looks like there is no command in git which keeps the history

I would suggest to use
cp en/<doc>.rst doc/lang/<doc>.rst

Regards

Astrid
