it has been moved to `yast-installation-control-openSUSE`, it's called a template, but in fact it is used in the [skelcd-control-openSUSE-LangAddOn](https://build.opensuse.org/package/view_file/openSUSE:Factory/skelcd-control-openSUSE-LangAddOn/installation.xml?expand=1) without any change.

(Uh, I just noticed that there is a different `textdomain` in Factory, but IMHO it's a bug, I'll sync the files...)
