[influxdb] helm_charts influxdb, backup_cronjob template has misconfiguration.

```
- name: AZURE_STORAGE_CONNECTION_STRING
valueFrom:
secretKeyRef:
name: {{ .Values.backup.azure.storageAccountSecret }}
key: connection-string
```

the template causes it to fail with below error `spec.jobTemplate.spec.template.spec.containers[0].env[3].valueFrom.secretKeyRef.name: Invalid value: `

Locate the InfluxDB Helm chart's backup_cronjob template and inspect the Azure storage secretKeyRef shown in the report. Render or install the chart with Azure backup settings, then verify that the generated Job has a valid secret name and no longer produces the reported Kubernetes validation error.
