A partir desse link "gtype" parece bom procurar no banco de dados yum
$ yum whatprovides '*/gobject/*' | egrep 'gtype.*html'
Filename : /usr/share/gtk-doc/html/gobject/gtype-non-instantiable.html
Filename : /usr/share/gtk-doc/html/gobject/gtype-non-instantiable-classed.html
Filename : /usr/share/gtk-doc/html/gobject/chapter-gtype.html
Filename : /usr/share/gtk-doc/html/gobject/gtype-instantiable-classed.html
Filename : /usr/share/gtk-doc/html/gobject/gtype-conventions.html
chapter-gtype.html
parece um bom sucesso, então
$ yum whatprovides /usr/share/gtk-doc/html/gobject/chapter-gtype.html
...
glib2-doc-2.54.2-2.el7.noarch : A library of handy utility functions
Repo : base
Matched from:
Filename : /usr/share/gtk-doc/html/gobject/chapter-gtype.html
então é provavelmente o pacote glib2-doc
