It also blocks PR merging since PR checks are failing like here #19606

The source of the problem is TLS1.0 that was used in fabric8io/kubernetes-client#3038 and removed in java 11.0.11 https://bugs.openjdk.java.net/browse/JDK-8202343 Since we used actions/setup-java@v1 on github actions we got the latest version of java 11. At this point the safest thing to wait for fix fabric8io/kubernetes-client#3038 and backport if needed to kubernetes-client 4.x after that align github action version with the version of java that we use for che-server docker image build
