Description

The CRD upgrade documentation (https://nightlies.apache.org/flink/flink-kubernetes-operator-docs-main/docs/operations/upgrade/). only deals with the case of breaking CRD changes.

It would be important to add a section detailing the regular CRD install/upgrade process using kubectl create/replace as apply simply does not work with a large CRD like this as seen for example here: https://issues.apache.org/jira/browse/FLINK-27288
