[maven-release-plugin] prepare release ebean-11.18.3

* Fix: apply drop checkConstraints properly which were not applied for Enum to String

* Use IF EXISTS to drop constraints

* added TODO and comment about MariaDB supporting CHECK constraints from version 10.2.1 forward compared to MySQL 5.7/8.0 parsing but ignoring CHECK constraints

* updated reference scripts for dropping constraints on enums
