Issue Description

The helm chart should set the namespace deployed to under the metadata.namespace field as the registry operator does: https://github.com/devfile/registry-operator/blob/f55ab8e7c8061934547c7d55bd67d81d509a8752/pkg/registry/configmap.go#L62

Parent Epic: #1274

Acceptance Criteria

• Set metadata.namespace under configmap.yaml
• Set metadata.namespace under deployment.yaml
• Set metadata.namespace under ingress.yaml
• Set metadata.namespace under pvc.yaml
• Set metadata.namespace under route.yaml
• Set metadata.namespace under service.yaml
• Verify changes in a deployment

[michael-valdron]

Set metadata.namespace in all helm chart template specs, verifying changes under OpenShift 4.13 and Kubernetes 1.26 (minikube)

Deployment is success under minikube and metadata.namespace appears to be set correctly under deployed specs (deployed under default namespace in this case):
