Procedures to verify upgrade of OpenShift Logging v5.3+ in docs are incorrect

Document URL:

• Updating OpenShift Logging
  [
  https://docs.openshift.com/container-platform/4.10/logging/cluster-logging-upgrading.html
  ]

Section Number and Name:

• Updating OpenShift Logging to the current version
  [
  https://docs.openshift.com/container-platform/4.10/logging/cluster-logging-upgrading.html#cluster-logging-updating-logging-to-5-1_cluster-logging-upgrading
  ]

The incorrect procedure is in "3. Check the logging components:" of the above section.
~~~
e. Verify that the log collector is updated to 5.x:

$ oc get ds fluentd -o json | grep fluentd-init

Verify that the output includes a fluentd-init container:

"containerName": "fluentd-init"
~~~

Describe the issue:

As of OpenShift Logging v5.3, the data collector component name has been replaced "fluentd" with "collector".
But our docs do not consider this change in the procedures to verify it after upgrade of it.
So we should provide the correct procedure to verify the collector pod after upgrade in the docs.

You can see the background of changing the component name from here:
https://issues.redhat.com/browse/LOG-1337
Suggestions for improvement:

For example, my suggestion is as follows.
~~~
e. Verify that the log collector is updated to it before 5.3:

$ oc get ds fluentd -o json | grep fluentd-init

Verify that the output includes a fluentd-init container:

"containerName": "fluentd-init"

f. Verify that the log collector is updated to it as of 5.3:

$ oc get ds collector -o json | grep collector

Verify that the output includes a collector container:

"containerName": "collector"
~~~
