[BUG] Missing snapshotRepositories in Helm Chart (opensearch-cluster) Template

What is the bug?

The Helm chart for the OpenSearch Cluster is missing the snapshotRepositories configuration in the template file. This is causing issues when trying to configure S3 snapshot repositories through the Helm chart.

How can one reproduce the bug?

1: Configure the values.yaml file with the snapshotRepositories section as shown below:

opensearchCluster:
  enabled: true
  general:
    httpPort: "9200"
    version: 2.3.0
    serviceName: "my-cluster"
    drainDataNodes: true
    setVMMaxMapCount: true
    pluginsList: ["repository-s3"]
    keystore:
    - secret:
        name: aws-keys
      keyMappings:
        access: s3.client.default.access_key
        secret: s3.client.default.secret_key
    snapshotRepositories: 
        - name: my_s3_repository
          type: s3
          settings:
            bucket: kanzal-test
            region: ap-southeast-2
            base_path: new-snapshots

  dashboards:
    enable: true
    replicas: 1
    version: 2.3.0
    resources:
      requests:
        memory: "1Gi"
        cpu: "500m"
      limits:
        memory: "1Gi"
        cpu: "500m"
  nodePools:
    - component: masters
      diskSize: "30Gi"
      replicas: 3
      roles:
        - "master"
        - "data"
      resources:
        requests:
          memory: "2Gi"
          cpu: "500m"
        limits:
          memory: "2Gi"
          cpu: "500m"
  security:
    tls:
      transport:
        generate: true
      http:
        generate: true

2: Run the helm template command.

Actual Result

The output of the helm template command does not include the snapshotRepositories section in the rendered YAML. Below is the rendered YAML:

---
# Source: opensearch-cluster/templates/opensearch-cluster-cr.yaml
apiVersion: opensearch.opster.io/v1
kind: OpenSearchCluster
metadata:
  name: release-name
  namespace: default
spec:
  general:
    version: 2.3.0
    httpPort: 9200
    vendor: opensearch
    serviceName: my-cluster
    pluginsList:

      - repository-s3
    keystore:

      - keyMappings:
          access: s3.client.default.access_key
          secret: s3.client.default.secret_key
        secret:
          name: aws-keys
    setVMMaxMapCount: true
    drainDataNodes: true
  dashboards:
    version: 2.3.0
    enable: true
    replicas: 1
    resources:
      requests:
        memory: 1Gi
        cpu: 500m
      limits:
        memory: 1Gi
        cpu: 500m
  nodePools:
    - component: masters
      replicas: 3
      diskSize: "30Gi"
      resources:
        requests:
          memory: 2Gi
          cpu: 500m
        limits:
          memory: 2Gi
          cpu: 500m
      roles:

      - master
      - data
  security:
    tls:
      transport:
        generate: true
      http:
        generate: true

What is the expected behavior?

The output of the helm template command should include the snapshotRepositories section in the rendered YAML. Below is the expected rendered YAML:
