Broken link in online docs - GdkRGBA

[Daniel Kasak <d j kasak dk gmail com>]

Hi all.

At https://developer.gnome.org/gtk3/stable/GtkColorButton.html#GtkColorButton--rgba
there is a broken link for GdkRGBA.

I guess it should be:
https://developer.gnome.org/gdk3/stable/gdk3-RGBA-Colors.html

 ... but is:
https://developer.gnome.org/gtk3/gdk4/gdk4-RGBA-Colors.html#GdkRGBA
