🐛 Update inaccurate RHBK task names (#534)

<!-- This is an auto-generated comment: release notes by coderabbit.ai
-->
## Summary by CodeRabbit

* **Changes**
* Set RHBK deployment replica count to 1 during secret resource
preparation (previously 0), ensuring resources are prepared without
conditional readiness constraints.
* Switched RHBK Keycloak operation from "Create" to "Update" to make the
configuration apply idempotently and reflect ongoing updates.
