Make exception for CPU images that have to stay IBM compatible (Power/Z):

How Has This Been Tested?

Self checklist (all need to be checked):

• Ensure that you have run make test (gmake on macOS) before asking for review
• Changes to everything except Dockerfile.konflux files should be done in odh/notebooks and automatically synced to rhds/notebooks. For Konflux-specific changes, modify Dockerfile.konflux files directly in rhds/notebooks as these require special attention in the downstream repository and flow to the upcoming RHOAI release.

Merge criteria:

• The commits are squashed in a cohesive manner and have meaningful messages.
• Testing instructions have been added in the PR body (for PRs involving changes that are not immediately obvious).
• The developer has manually tested the changes and verified that the changes work

@ysok I can't do this, the 3.0 images that still have IBM arches support don't have their own repos in them. AIPCC first removed IBM arches support and only then started preserving repo files in /etc/yum.repos.d/

[ysok]

@jiridanek it was ubi9 that has those repos (may included IBM?), but since we switched to aipcc, it is RHEL9.

I've tried both cpu:3.0-1761580156 and cpu:3.1-1762903336, since they don't have subcription manager, dnf upgrade did shrink their /etc/yum.repos.d/redhat.repo to almost empty, no enabled repos. We have to change and test each dockerfile with AIPCC image to make sure they can be built successfully, I had to use mcurlej's copr.

`podman run --rm -it --platform linux/x86_64 --user root quay.io/aipcc/base-images/cpu:3.1-1762903336 bash -c "ls -alh /etc/yum.repos.d/redhat.repo && dnf upgrade || true && ls -alh /etc/yum.repos.d/redhat.repo"
