Align contextPath config for secret service with similar configurations

1. EDS Service repo https://community.opengroup.org/osdu/platform/data-flow/ingestion/external-data-sources/eds-dms/-/blob/master/devops/azure/chart/helm-config.yaml?ref_type=heads#L88
   value: /api/eds/v1/

2. EDS Helm repo https://community.opengroup.org/osdu/platform/deployment-and-operations/helm-charts-azure/-/blob/master/osdu-azure/eds-dms/values.yaml?ref_type=heads#L104
   value: /api/eds/v1/

3. Secret Service repo https://community.opengroup.org/osdu/platform/security-and-compliance/secret/-/blob/main/devops/azure/chart/helm-config.yaml?ref_type=heads#L95
   value: /api/secret/v1/

4. Secret Helm repo https://community.opengroup.org/osdu/platform/deployment-and-operations/helm-charts-azure/-/blob/master/osdu-azure/secret/values.yaml?ref_type=heads#L108
   value: /api/secret/

It seems configuration 4 is not aligned wiht the pattern. Fixing this for Secret service.
