Subject: [PATCH 2/2] gnu: fcitx5-gtk: Split IM module output for different
 version of GTK.

* gnu/packages/fcitx5.scm (fcitx5-gtk)[arguments] <phases>: Split input method
module into different outputs for GTK2, GTK3 and GTK4.

Now default output only provides GLib client of Fcitx5.

[outputs]: Add new "gtk3" output.
