docker: Update Dovecot config to 2.4

Browse Source 
Debian 13, the new stable version, updated Dovecot from 2.3 to 2.4.
Unfortunately, the new Dovecot version introduced several changes to the
configuration file that are not backwards-compatible.

https://doc.dovecot.org/2.4.2/installation/upgrade/2.3-to-2.4.html

This patch updates our docker's Dovecot config to the new version.

Thanks to Ernesto Alfonso (erjoalgo@github) for reporting this problem
in https://github.com/albertito/chasquid/issues/80.
