fix(gnome): enable gtk and qt theming in home manager

Without GTK theming explicitly enabled in the GNOME home manager module, GNOME fails to inherit the dconf settings for the configured cursor and icon themes (falling back to missing or default cursors). This change ensures GNOME automatically applies khanelinix.theme.gtk and khanelinix.theme.qt, matching the behavior of WM modules (like Hyprland).
