fix: operator deployment ignores custom namespace

[timmhirsens]

Description

This fixes the operator deployment actually using the namespace defined in the helm values. Without this fix, the deployment will fail, since the configuration ConfigMap for the operator is deployed in the specified namespace while the operator itself is deployed in kube-system.
