Update cluster-logging-collector-limits.adoc

Wrong command in logging 6 documentation
Here is the documentation link:
 https://docs.redhat.com/en/documentation/red_hat_openshift_logging/6.3/html/configuring_logging/cluster-logging-collector#cluster-logging-collector-limits_cluster-logging-collector
Current Look:

Edit the ClusterLogForwarder CR in the openshift-logging project:
$ oc -n openshift-logging edit ClusterLogging instance
This is a command referencing the `ClusterLogging` instance
But here we are editing the ClusterLogForwarder CR in the openshift-logging project.
Hence, it needs to be changed with ClusterLogForwarder or obsclf.
Updated Look:

Edit the ClusterLogForwarder CR in the openshift-logging project:
$ oc -n openshift-logging edit clusterlogforwarder.observability.openshift.io <clf_name>
This is the correct format.
