[aur-general] development version for gnome dependencies in aur

[Ionuț Bîru]

Hi,

i've seen a lot of _new_ builds submitted in aur mostly related to 
gnome-shell 2.91. This is duplicating my work and makes in the same time 
is hard for users to test the future gnome 3 version and updating to 
gnome-unstable/testing/extra at some point.

I would start deleting _all_ builds related to gnome3/gnome-shell 
tomorrow. STOP uploading it.
