For split out gnome-getting-started-docs-*, these need to be added to data/pkg_depends in language-selector. Indeed that doesn't care about the component, universe packages are fine. Please set a "trigger" package for installing them, so that these are only installed if you actually have Ubuntu GNOME installed. E. g.
tr::gnome-session:gnome-getting-started-docs-
Presumably gnome-session is not the best trigger package, maybe there's something like gnome-help?
