### Expected/desired behavior
> The install of CAPZ relies on the natural available mechanisms for installation with ArgoCD versus the[ pre-sync sleep hook](https://github.com/Azure-Samples/aks-platform-engineering/blob/a06b3f9c804b68146082f5ee942626437cc53252/gitops/bootstrap/control-plane/addons/azure/addons-azure-cluster-api-operator.yaml#L45-L47) which points to [sleep hook file](https://github.com/Azure-Samples/aks-platform-engineering/blob/main/gitops/hooks/sleep/sleep.yaml).

2. [Progressive Syncs](https://argo-cd.readthedocs.io/en/stable/operator-manual/applicationset/Progressive-Syncs/)
