emilylange b7d2f287f3 docs/dovecot: fix dovecot URLs (again)
https://doc.dovecot.org/configuration_manual moved to
https://doc.dovecot.org/2.3/configuration_manual to make room for
https://doc.dovecot.org/:version/ where :version can be any one of 2.3,
2.4.0, 2.4.1 or main.

Unfortunately, there is no redirect for the 2.3 manual pages, rendering
a few of those dovecot links dead. I figured we want to keep the old
docs at /2.3/ for now until we eventually migrate to 2.4, as there are
some differences in the ldap interface between those versions.
