gtk:shortcuts-group-add-shortcut (group shortcut)

group -- a gtk:shortcuts-group widget
shortcut -- a gtk:shortcuts-shortcut widget

Adds a shortcut to the shortcuts group. This is the programmatic equivalent to using a gtk:builder UI definition and a <child> tag to add the child. Adding children with other API is not appropriate as the gtk:shortcuts-group widget manages its children internally.
