upgrade jobs (1.1.1 to main) are broken due to flux CRD changes

Summary

The issue has been observed in https://gitlab.com/sylva-projects/sylva-core/-/jobs/7501990524

📜 Update sylva-units Helm release and associated resources

Warning: resource namespaces/sylva-system is missing the kubectl.kubernetes.io/last-applied-configuration annotation which is required by kubectl apply. kubectl apply should only be used on resources created declaratively by either kubectl create --save-config or kubectl apply. The missing annotation will be patched automatically.

error: resource mapping not found for name: "sylva-units" namespace: "sylva-system" from "STDIN": no matches for kind "HelmRelease" in version "helm.toolkit.fluxcd.io/v2"
ensure CRDs are installed first

We should figure-out a way to properly handle this case in our scripts.
