GtkFileChooser: reference documentation for {add,remove,set,get}_choice is not generated (gtk3 only)
The functions gtk_file_chooser_{add,remove,set,get}_choice were added to both Gtk4 and Gtk3. But Gtk3 reference documentation does not list the functions: https://developer.gnome.org/gtk3/stable/GtkFileChooser.html. This is because of a small typo.
Fix the documenting block from /** ... */
to /** ... **/
to generate documentation for the functions
Add the functions to docs/reference/gtk/gtk3-sections.txt
