One step needs to be added to the Quick Start point of About Logging 6.0 documentation

- One step needs to be added to the Quick Start point of About Logging 6.0 documentation.
- Here is the documentation link: https://docs.openshift.com/container-platform/4.17/observability/logging/logging-6.0/log6x-about.html#quick-start
- Here Step 2 is mentioned as "Create a LokiStack custom resource (CR) in the openshift-logging namespace:"
- But before creating `LokiStack` custom resource (CR), it is necessary to create an `object storage secret`.
- Without creating a secret we can not create `Lokistack` customer resource.
- We need to mention that `object storage secret` name in the `LokiStack custom resource (CR)` under `spec.storage.secret.name` section.
- So it is required to add this step in our documentation.
- Hence adding Step 2 in the documentation:

-----------------
2.  Create a secret to access an existing object storage bucket:
Example command for AWS
~~~
$ oc create secret generic logging-loki-s3 \
  --from-literal=bucketnames="<bucket_name>" \
  --from-literal=endpoint="<aws_bucket_endpoint>" \
  --from-literal=access_key_id="<aws_access_key_id>" \
  --from-literal=access_key_secret="<aws_access_key_secret>" \
  --from-literal=region="<aws_region_of_your_bucket>" \
  -n openshift-logging
~~~
