Tag scenarios that rely on the shipped documentation
As decided in #10492 (closed), we don’t want to run the whole test suite on branches that only change the Tails documentation, but only scenarios that relies on the documentation shipped within Tails.
The chosen implementation requires us to mark this kind of scenarios as
doc in order to do so.
Feature Branch: Tails:test/10706-add-doc-tags
Parent Task: sysadmin#10153 (closed)
