  v2 removal on restore does not cover HTTPS services
  The logic added in https://github.com/freedomofpress/securedrop/pull/5677 to disable v2 onion services when a backup is restored to a Focal server does not remove config lines for HTTPS services (port 443), potentially resulting in a broken configuration.
