local-storage-operator is unavailable in OKD 4

[OleksandrShtepa]

Describe the bug
Regarding OKD 4 docs Persistent storage using local volumes:

The Local Storage Operator is not installed in OKD by default. Use the following procedure to install and configure this Operator to enable local volumes in your cluster.

I tried to install local-storage-operator, but any my actions was not successfully.

From the UI
2. Navigate to Operators → OperatorHub.
3. Type Local Storage into the filter box to locate the Local Storage Operator.

No Results Match the Filter Criteria

From the CLI
2. Create the Local Storage Operator object by entering the following command:
$ oc apply -f openshift-local-storage.yaml

got:

$ oc describe subscriptions local-storage-operator -n openshift-local-storage
Status:
  Conditions:
    Last Transition Time:  2021-04-08T07:35:13Z
    Message:               targeted catalogsource openshift-marketplace/redhat-operators missing
    Reason:                UnhealthyCatalogSourceFound

On fresh installed OKD 4.7 I have:

$ oc describe operatorhubs cluster
Spec:
  Disable All Default Sources:  true
  Sources:
    Disabled:  false
    Name:      community-operators
$ oc get packagemanifests -n openshift-marketplace|fgrep -i local
$

Version

after upgrading my OKD cluster to 4.14 I needed to disable and then re-enable all the sources in Cluster Settings->Configuration->OperatorHub details, click edit on Default sources, disable them and then enable them again. Now I can see both local storage and data foundation operators
