Remove CRD update from Helm chart upgrade job

Helm chart upgrade Job (stackgres-k8s/install/helm/stackgres-operator/templates/upgrade-job.yaml) runs before the CRD upgrade Job (stackgres-k8s/install/helm/stackgres-operator/templates/crd-upgrade-job.yaml) and is updating the CRDs with the following commands:

            {{- range $path, $_ := .Files.Glob "crds/*" }}
            cat << 'EOF' > /tmp/crd.yaml
{{ $.Files.Get $path | indent 12 }}
            EOF
            kubectl apply -f /tmp/crd.yaml
            {{- end }}

Since the Helm chart CRD upgrade Job is already performing the Job of updating the CRDs we want to not repeat that Job.

Implementation plan

Remove update of CRDs from Helm chart upgrade Job (stackgres-k8s/install/helm/stackgres-operator/templates/upgrade-job.yaml).

Acceptance Criteria

The upgrade of CRDs still work as expected and dbops-security-upgrade test does not fail.
