* fix: Let operator deploy listener class presets

* chore: Use fixed stackable-operator version

 ### Changed
 
+- The operator now deploys the selected ListenerClass preset instead of relying on Helm ([#369]).
+  - This mechanism is currently tied to CRD maintenance.
 - Gracefully shutdown all concurrent tasks by forwarding the SIGTERM signal ([#366]).
 - OLM deployer doesn't add owner references to cluster scoped objects anymore ([#360]).
   Owner references ensure that objects are garbage collected by OpenShift upon operator removal but they cause problems when the operator is updated.
