Hi, I noticed that the newest documentation of the flink-operator has pointed to v1.6.0, yet when using the `helm repo add flink-operator-repo https://downloads.apache.org/flink/flink-kubernetes-operator-1.6.0/` command to install, it turns out that the given URL does not exist.
I suppose that 1.6.0 is not ready and the documentation( https://nightlies.apache.org/flink/flink-kubernetes-operator-docs-stable/) should point to 1.5.0 ?
