Gluster users - Jun 2022 - Debian repository instructions outdated

Hello all.

The instructions given f.e. at [1] do not follow the Debian instructions 
for 3rdparty repositories [2] .

Mostly it boils down to changing the first step to:
mkdir /etc/apt/keyrings
curl https://download.gluster.org/pub/gluster/glusterfs/9/rsa.pub | gpg 
--dearmor > /etc/apt/keyrings/gluster-archive-keyring.gpg
and then add 'signed-by=/etc/apt/keyrings/gluster-archive-keyring.gpg' 
between '[' and 'arch=amd64'.

HIH,
  Diego
