How to configure Loki Object Storage CA certificate in RHOCP 4

Issue

• How to configure the Certificate Authority (CA) certificate for the ObjectStorage endpoint in the LokiStack?
• After installing the Network Observability Operator using the SSL/TLS protocol, an error with the CA trust certificate occurs while Loki Operator attempts to save data on a S3 bucket using a customized certificate.

• Errors while flushing to the ObjectStorage backend:

  msg="failed to flush" err="failed to flush chunks: store put chunk: RequestError: send request failed\ncaused by: Put \"https://objectstorage.example.com:1234/loki-storage/backend\": tls: failed to verify certificate: x509: certificate signed by unknown authority
  

  msg="failed to flush" err="failed to flush chunks: store put chunk: RequestError: send request failed\ncaused by: Put \"https://objectstorage.example.com:1234/loki-storage/backend\": tls: failed to verify certificate: x509: certificate relies on legacy Common Name field, use SANs instead
  

• Error message in the LokiStack status:

      message: 'Invalid object storage CA configmap contents: key not present or data
        empty: service-ca.crt'
