Subject: document GuixSD system recovery process + document bournish and recovery/guile repl

Currently neither bournish nor the guile recovery repl are documented
in a way which is helpful for a person which isn't technical
knowledged running into the unhappy case of a system which doesn't
boot. In fact both are not even mentioned in our documentation
and the built in help is not sufficient.
