Workload Dashboard not gracefully handling the NaN values

When a namespace has a Resource Quota applied to it the Workload Graphs in the Observe view does not renders properly.

1. Create a new project/namespace
2. Apply the following Resource Quota (just a sample) to it
```
kind: ResourceQuota
apiVersion: v1
metadata:
  name: staging-workshop-quota
spec:
  hard:
    limits.cpu: '3'
    limits.memory: 3Gi
    pods: '10'
```
3. From the Developer Console, access the Observe View 3. From teh Dashboard list, select `Kubernetes / Compute Resources / Namespaces (Workloads)` Option 

The Graph is not rendered (see attached screenshot)

The Graph should render even with no data point

When you have a Resource Quota applied to the namespace you can try this query to see the `NaN` value returned.

```
curl -G -s -k -H "Authorization: Bearer $(oc whoami -t)" 'https://thanos-querier-openshift-monitoring.apps.cluster-your cluster domain here/api/v1/query' --data-urlencode 'query=scalar(kube_resourcequota{cluster="", namespace="user9-staging", type="hard",resource="requests.memory"})'
```

sample respose
```
{"status":"success","data":{"resultType":"scalar","result":[1682600794.396,"NaN"]}}
```
