[IBI][Doc] The example to add a CA bundle in an image-based deployment seems to be misleading.

Looking under this link:

https://79610--ocpdocs-pr.netlify.app/openshift-enterprise/latest/edge_computing/image_base_install/ibi_deploying_sno_clusters/ibi-edge-image-based-install#ibi-create-ca-extra-manifest-configmap_ibi-edge-image-based-install

There's this step:

Create the ConfigMap object by running the following command:$ oc create configmap custom-ca --from-file=example-ca.crt -n ibi-ns 

The above example will create a configmap with the key example-ca.crt

Yet, if we look at the ImageClusterInstall explanation for spec.caBundleRef - it says:

  caBundleRef   <Object>
    CABundle is a reference to a config map containing the new bundle of trusted
    certificates for the host.
    The tls-ca-bundle.pem entry in the config map will be written to
    /etc/pki/ca-trust/extracted/pem/tls-ca-bundle.pem
 

The above suggests that the file name in the example should be tls-ca-bundle.pem (or the argument to --from-file has to include the key name as well)
