CRDs not updated when upgrading from v5.5.x to v6.x

[54nd20]

When upgrading from v5.5.x to v6.x argocd is updated to v2.9.2 but the CRDs are not updated. In particular CRD "applications.argoproj.io" needs to be updated. If that is not done, we run into issue argoproj/argo-cd#15220 which leads to very high CPU usage and the following warning messages in the log of the argocd application controller:

W0216 16:49:14.378592       1 warnings.go:70] unknown field "status.controllerNamespace"
W0216 16:49:14.378615       1 warnings.go:70] unknown field "status.sync.comparedTo.ignoreDifferences"

Change in CPU usage after updating the CRD "applications.argoproj.io":

Steps to Reproduce the Problem
