Sets the alignment of the lines in the text of the label relative to
each other.
%GTK_JUSTIFY_LEFT is the default value when the widget is first created
with [ctor@Gtk.Label.new]. If you instead want to set the alignment of
the label as a whole, use [method@Gtk.Widget.set_halign] instead.
[method@Gtk.Label.set_justify] has no effect on labels containing
only a single line.
