    po: fix desktop file keywords syntax for Basque translation.
    
    Some tool in flatpak-build was failing to validate the keywords because
    of this localization. It was complaining that:
    
    > key "Keywords[eu]" in group "Desktop Entry" does not have a semicolon
    > (';') as trailing character
