Update distr-tracing-tempo-object-storage-setup-ibm-storage.adoc

- Incorrect command structure in the Object storage setup documentation.
- Here is the documentation link:
https://docs.redhat.com/en/documentation/openshift_container_platform/4.15/html/distributed_tracing/distributed-tracing-platform-tempo#distr-tracing-tempo-object-storage-setup-ibm-storage_dist-tracing-tempo-installing

- In the above commands, the "- -" signs are incorrectly placed below the "$" symbol.
- However, they should be aligned parallel to the "ibmcloud" command, where the command begins.

- Here is the updated look for all these commands:

1. On IBM Cloud, create a service key for connecting to the object store bucket by running the following command:
~~~
$ ibmcloud resource service-key-create <tempo_bucket> Writer \
  --instance-name <tempo_bucket> --parameters '{"HMAC":true}'
~~~
