Document the entire weblate installation & setup process
We want to be able to redo this if necessary, so ideally we’d like to have a documented & tested setup process.
A great part of the setup is documented in Puppet: https://git-tails.immerda.ch/puppet-tails/tree/manifests/weblate.pp
Feature Branch: translate-server.git:master
