gnome3.gnome-{control-center,settings-daemon,shell} ship within their
tarball a copy of lignome-volume-control in the `subprojects/gvc/`. This
commit makes them use an updated version of it, which supports Modern
laptops with SOF for audio. Close#98470.
Opening a background change dialogue produces the following errors in the console:

Apparently, there are no plugins in `grilo` package – everything is in `grilo-plugins`, so we need to add `grilo-plugins` to inputs. The setup hook will make the plug-ins available through an environment variable:
https://gitlab.gnome.org/GNOME/grilo/blob/grilo-0.3.9/src/grilo.c#L111-135
This is needed for its gnome-version.xml so it can properly display
the current gnome-desktop version in the info panel.
Previously it was always "GNOME 3.0".
Just like Nautilus (see #29970), GNOME Control Center also uses
gnome-desktop for generating thumbnails. In particular, it tries
to make a thumbnail from a file choosen as a profile picture, and
when it does not succeed, it will not allow that file to be chosen.
Of course, whithout a thumbnailer, it will always fail.
43129a1cfd/panels/user-accounts/um-photo-dialog.c (L190-L192)
Since gnome-desktop scans `thumbnailers` directories under the paths
in `XDG_DATA_DIRS`, gdk-pixbuf had to be added to the path to provide
access to image thumbnailer.
* gnome3: only maintain single GNOME 3 package set
GNOME 3 was split into 3.10 and 3.12 in #2694. Unfortunately, we barely have the resources
to update a single version of GNOME. Maintaining multiple versions just does not make sense.
Additionally, it makes viewing history using most Git tools bothersome.
This commit renames `pkgs/desktops/gnome-3/3.24` to `pkgs/desktops/gnome-3`, removes
the config variable for choosing packageset (`environment.gnome3.packageSet`), updates
the hint in maintainer script, and removes the `gnome3_24` derivation from `all-packages.nix`.
Closes: #29329
* maintainers/scripts/gnome: Use fixed GNOME 3 directory
Since we now allow only a single GNOME 3 package set, specifying
the working directory is not necessary.
This commit sets the directory to `pkgs/desktops/gnome-3`.
