New installation method for Debian and Ubuntu

[jredrejo]

For security reasons, beginning in Debian 12 and Ubuntu 22.04, apt-key will trigger a deprecation message. The current installation methods explained in the docs will be deprecated in the future. The new method, valid both for Debian and Ubuntu is this one:

sudo gpg --keyserver hkp://keyserver.ubuntu.com:80 --recv-keys DC5BAA93F9E4AE4F0411F97C74F88ADB3194DD81
sudo gpg --output /usr/share/keyrings/learningequality-kolibri.gpg --export  DC5BAA93F9E4AE4F0411F97C74F88ADB3194DD81

sudo su -c 'echo "deb [signed-by=/usr/share/keyrings/learningequality-kolibri.gpg] http://ppa.launchpad.net/learningequality/kolibri/ubuntu jammy main" > /etc/apt/sources.list.d/learningequality-ubuntu-kolibri.list'

sudo apt-get update
sudo apt install kolibri

Docs at https://kolibri.readthedocs.io/en/latest/install/ubuntu-debian.html must reflect this change for these versions of Debian & Ubuntu and considered deprecated the previous methods , to be used only in old versions of these distributions.
