I am trying to build the operator image locally and fail because the registry `registry.ci.openshift.org/ocp/` requires authorization

1. git clone git@github.com:openshift/cluster-ingress-operator.git
2. export REPO=<path to a repository to upload the image>
3. run `make release-local`

[skip several lines]
Step 1/10 : FROM registry.ci.openshift.org/ocp/builder:rhel-8-golang-1.19-openshift-4.12 AS builder                                                                                             
unauthorized: authentication required 

image is pulled and the build succeeded

There are two images that are not available:
- registry.ci.openshift.org/ocp/builder:rhel-8-golang-1.19-openshift-4.12
- registry.ci.openshift.org/ocp/4.12:base

I was able to fix this by changing the images to
- registry.ci.openshift.org/openshift/release:golang-1.19                     - registry.ci.openshift.org/origin/4.12:base                                 

see https://github.com/dudinea/cluster-ingress-operator/tree/fix-build-images-not-public

I am not sure what I did is OK, but I suppose that this project,               being part of OKD should be easily buildable by the public
or at least the issue should be documented somewhere.                         
                                                        
I wanted to post this to the OKD project, but I am unable to select it in jira.
