Does this string ever get shown to users? If so, does it need to be localized?
If not, can we make it optional (I assume this is just for placeholder until the
actual app gets installed from the webstore)?

It seems this string isn't used at all, I added it because it's also there for
all the apps in
src/chrome/browser/extensions/default_extensions/chromeos/external_extensions.json,
but since it isn't actually used afaict I've just removed it.
