+- Added support for Trino 455 ([#638]).

 ### Changed
 
 - Reduce CRD size from `984KB` to `131KB` by accepting arbitrary YAML input instead of the underlying schema for the following fields ([#631]):

 - Don't ignore envOverrides ([#633]).
 - Don't print credentials to STDOUT during startup. Ideally we should use [config-utils](https://github.com/stackabletech/config-utils), but that's not easy (see [here](https://github.com/stackabletech/trino-operator/tree/fix/secret-printing)) ([#634]).
