Replace glade mention by UI file, maybe mention Cambalache as alternative
I haven't seen glade not being recommended in the gtkmm(-4) documentation, even though it is not actively maintained anymore and not ported to GTK4.
- https://gitlab.gnome.org/GNOME/glade#development-status
- https://discourse.gnome.org/t/plan-about-gtk4-support-of-glade/5965
- https://blogs.gnome.org/christopherdavis/2020/11/19/glade-not-recommended/
Also, maybe switch "glade file" term in the doc by "ui file" like it is now in the gtk doc: https://docs.gtk.org/gtk4/getting_started.html#populating-the-window
There is also Cambalache that supports GTK3 and GTK4: https://gitlab.gnome.org/jpu/cambalache
