Update logging-loki-storage-azure.adoc

Incorrect command structure in the Azure Object Store documentation
Here is the documentation link: 
https://docs.redhat.com/en/documentation/openshift_container_platform/4.15/html/logging/log-storage-3#logging-loki-storage-azure_installing-log-storage
Here is the current documentation look:

You can create the Loki object storage secret manually by running the following command:

$ oc -n openshift-logging create secret generic logging-loki-azure \
--from-literal=environment="<azure_environment>" \
--from-literal=account_name="<storage_account_name>" \
--from-literal=container="<container_name>" 
In the above command, the "- -" signs are incorrectly placed below the "$" symbol.
However, it should be aligned parallel to the "oc" command, where the command begins.
Here is the updated look for all these commands:

$ oc -n openshift-logging create secret generic logging-loki-azure \
  --from-literal=environment="<azure_environment>" \
  --from-literal=account_name="<storage_account_name>" \
  --from-literal=container="<container_name>" 
The commands will work as it is, but the structure is incorrect.
It should be a standard format all over the documentation.
