As part of our continuous improvement efforts, we need to update our Dockerfile to utilize the new multi-base images provided in OpenShift 4.18. The current Dockerfile is based on RHEL 8 and RHEL 9 builder images from OpenShift 4.17, and we want to ensure our builds are aligned with the latest supported images, for multiple architectures.

Updating the RHEL 9 builder image to

registry.ci.openshift.org/ocp/builder:rhel-9-golang-1.22-builder-multi-openshift-4.18

Updating the RHEL 8 builder image to

registry.ci.openshift.org/ocp/builder:rhel-8-golang-1.22-builder-multi-openshift-4.18

Updating the base image to

registry.ci.openshift.org/ocp-multi/4.18-art-latest-multi:machine-config-operator

or specifying a different tag if we dont want to only do mco

Ensuring all references and dependencies in the Dockerfile are compatible with these new images.
