docs: Note that supermaster support is off by default since 4.2

With commit b80139777ebd2e0dc14cfd88d30eed80cfc04054 / PR #6021, it appears
that the behaviour of PowerDNS has changed to not act as a supermaster any
longer by default. Having to add a new setting that did not exist before,
to retain the old behaviour should be mentioned, I believe.

 PowerDNS can recognize so called 'supermasters'. A supermaster is a host
 which is master for domains and for which we are to be a slave. When a
 master (re)loads a domain, it sends out a notification to its slaves.
