Bug#1100856: gnome-shell: System app folder missing for upgrades

[Jeremy Bícha]

Control: tags -1 trixie

The System app folder in GNOME Shell's Activities Overview does not
show for people who have upgraded from Debian 12 to Debian 13
"trixie". More specifically, if a user has logged in even once to
GNOME Shell before GNOME 48, they won't see the System app folder.

I believe this also happened for the Utilities folder years ago.

This also makes it awkward for us to customize these folders as
pointed in debian/changelog for gnome-shell  48.2-2

Thank you,
Jeremy Bícha
