Bug#1071383: gnome-core should recommend network-manager instead of network-manager-gnome

[jeremy.bicha at canonical.com]

Control: reopen -1
Control: reassign -1 task-gnome-desktop
Control: fixed gnome-core/1:47~beta+1
Control: forwarded -1 https://salsa.debian.org/installer-team/tasksel/-/merge_requests/31

I'm reopening and reassigning this issue since to fix this issue properly
as intended, we also need to get this fixed in tasksel. I submitted
a merge request to fix this and fix another unintended dependency,
and hopefully we will have less unintended dependencies in the future.

Thank you,
Jeremy Bícha
