Translation guide change

[gzordrai]

Describe the bug
Change ./Rofl.UI.Main/ to ../UI.Main/

python "compare-strings.py" `
    ..\Rofl.UI.Main\Resources\Strings `
    ..\Rofl.UI.Main\Resources\Strings\en.xaml

Maybe change the \ by / for those using linux (windows support / path)

[fraxiinus]

Hmm I suppose so. I usually use PowerShell which I think doesn't care between / and \

I will update the documentation still
