The Gtk.VBox documentation[1] says:

“Deprecated since version 3.2: You can use Gtk.Box.new() with
Gtk.Orientation.VERTICAL instead, which is a quick and easy change. But
the recommendation is to switch to Gtk.Grid, since Gtk.Box is going to
go away eventually. See Migrating from other containers to GtkGrid.”

Since no backwards incompatible change can be made in GTK+ 3.x, it is
still present as of 3.24, but it has been removed in 4.0 and it’d be
nice to support this one already when it’ll be released. :)
