Adding packages to ubuntu-desktop packageset

[Robie Basak]

I've added the following packages to ubuntu-desktop for you:

glycin
loupe
ptyxis
tecla
libnma
software-properties (software-properties-gtk is a binary produced by that source)
gstreamer1.0
gst-plugins-base1.0
gst-plugins-good1.0
gst-plugins-bad1.0
pulseaudio
pipewire
xwayland
xdg-terminal-exec
xdg-desktop-portal
xdg-desktop-portal-gtk

As I explained earlier in the thread, the following packages are not
seeded. That is, as far as I can tell from a quick glance - I don't have
tooling, so it's tedious and error prone - please correct me if I've
made a mistake. Therefore these appear unsuitable for the ubuntu-desktop
packageset:

gnome-kiosk
gnome-shell-extensions
gnome-terminal
showtime
gcr4
gnome-shell-ubuntu-extensions
gnome-shell-extension-gsconnect
gpaste
workrave
gnome-shell-pomodoro
gst-plugins-ugly1.0
gst-libav1.0
gstreamer-vaapi

If you want them to go into desktop-extra, then please explain how this
fits into the description "Every package that is NOT in ubuntu-desktop,
desktop-core or core, but needed for a vanilla GNOME" and how I can
validate that. Or if you want to be able to upload them but not through
those packagesets, then we can consider creating a different packageset
for them, but we'd 1) need a definition that we can rely on in future;
and 2) prospective uploaders would need to apply to the DMB for that
independently.

Thanks,

Robie
