Update health check for Fabric8 client 7.4.0

[metacosm]

The status is defined at the JOSDK level: https://github.com/operator-framework/java-operator-sdk/blob/main/operator-framework-core/src/main/java/io/javaoperatorsdk/operator/processing/event/source/informer/InformerWrapper.java#L204

Definitely need to refine that for 7.4.0+

Can you elaborate, please? Refine how? Why?

Please see fabric8io/kubernetes-client#7309 (comment)
