Public bug reported:

Test Case
---------
1. From Ubuntu 20.04 LTS or 21.10, open the Settings app. Click Appearance and 
choose Dark
2. Upgrade to Ubuntu 22.04 LTS
3. Your apps should still be dark

Linked Issue
------------
That test case is broken by the libhandy update. See LP: #1964841

We are updating gnome-control-center to set the correct gsettings value
(below) when choosing a dark theme.

Implementation
--------------
We need to set gsettings org.gnome.desktop.interface color-scheme 'prefer-dark' 
for users using a theme name ending in "-dark"

That gsettings schema is provided by gsettings-desktop-schemas.

I don't think we should do this in ubuntu-settings because there are
people using GTK desktops that don't have ubuntu-settings installed.

I suggest we use dh-migrations/session-migration to do this from gnome-
settings-daemon.

Let me know now if there is a better place for this.
