### What problem does this PR solve?

Fix a small non-blocking main workflow bug about chunk update When
OpenSearch is the doc engine.
When you wanna enable/disable a chunk in the web-page “Knowledge Base /
Dataset / Chunk”, the bug ocurred.

src="https://github.com/user-attachments/assets/575987a0-c929-4589-bfa0-ba54e137cfd9"
/>

The reaseon why it ocurred is that some api params between OpenSearch
and ES differs. It functioned well no matter enable/disable/rewrite the
chunk after I fixed. I also checked the result when using the chat
web-page.

I will still focus on vector-database espeically OpenSearch.

### What problem does this PR solve?

Previous version created labels which were dependent on the specific
Helm chart version such as:
```
volumeClaimTemplates:
- metadata:
    name: redis-data
    labels:
      helm.sh/chart: ragflow-0.2.3-dev.0.opensearch-test.4
      app.kubernetes.io/name: ragflow
      app.kubernetes.io/instance: test-1
      app.kubernetes.io/version: "9a04408"
      app.kubernetes.io/managed-by: Helm
      app.kubernetes.io/component: redis
```
which causes `helm upgrade` commands to fail with
```
Upgrade "test-1" failed: cannot patch "test-1-ragflow-redis" with
kind StatefulSet: StatefulSet.apps "test-1-ragflow-redis" is
invalid: spec: Forbidden: updates to statefulset spec for fields
other than 'replicas', 'ordinals', 'template', 'updateStrategy',
'persistentVolumeClaimRetentionPolicy' and 'minReadySeconds' are
forbidden
```
because the labels changed on upgrade.

This fix uses a reduced set of labels to prevent upgrade failures.
