Subject: [PATCH] dbus-interfaces: Update MalcontentTimer child interface

Update org.freedesktop.MalcontentTimer1.Child interface to include the
new screen time extensions functionality.

The interface has been updated from https://gitlab.freedesktop.org/pwithnall/malcontent/-/blob/main/libmalcontent-timer/org.freedesktop.MalcontentTimer1.Child.xml,
and it has not been modified after being copied.

Part-of: <https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/3999>
