Cannot Modify ClusterRole due to ClusterRoleBinding roleRef Immutable Field

[padraigmc]

In the Kraan Helm chart, the roleRef attribute in ClusterRoleBinding is immutable. If the ClusterRole name changes, it leads to a bug because the ClusterRoleBinding cannot be updated with the new ClusterRole name.

To fix this issue, we need to make the ClusterRoleBinding name configurable with a default name. This change will force Helm to delete and recreate the ClusterRoleBinding whenever there is a name change, ensuring the correct ClusterRole is referenced.
