"enable the Puppet Collection package repository" links to a 404, aka this
does not exist: "https://docs.puppet.com/puppet/6.4/puppet_collections.html",
and in another place it lists this as "Puppet Platform package repository".
What is the difference between "Puppet Platform package repository" and
"Puppet Collection package repository"? Frankly what is Puppet Platform and
what is Puppet Collection? I have used puppet for 7 years, and am updating
to puppet 6 from 2.7, this does not make sense to a user with 7 years of old
