chore(infra-apps): update argocd to 4.0.*

[eyenx]

Description

Updates infra-apps to use argocd chart version 4.0.*

With the 4.0 release of the chart controller.enableStatefulSet is true per default to enable HA mode. If you want to keep using a deploymet you need to set it to false.
Also both the ApplicationSet and Notifications controller are now deployed as part of Argo CD, this will need additional resources in the cluster.
Please tune applicationSet.metrics and applicationSet.resources as well as notifications.metrics, notifications.resources, and (maybe) notifications.argocdUrl during this upgrade at the very least.
