openshift/os: Explicitly promote into ocp/4.12 imagestream

[cgwalters]

Followup to openshift/os#940

We changed the image name, but to succeed in landing the MCO changes
to use rhel-coreos-8 we need an image named rhel-coreos-8 in
the integration imagestream.

Closes: openshift/os#943

Since this does touch image-mirroring, it appears we need an owner from there to also take a look.

For context, this is changing how we ship base OS images in alignment with the CoreOS Layering enhancement. The original (machine-os-content) will still be shipped for compatibility, but we need 2 additional images (rhel coreos 8 and extensions) for the new layered container image os format.

is this something you can help us with? Sorry for the multi-pings. This is blocking the MCO team and the layering initiative. For more context please see the above message (and openshift/machine-config-operator#3258 (comment) )
