just a quick comment. could be silly so please let me know but im wondering if this would affect the github runners and just in general? weve been noticing github slowing down here and there especially as we have been increasing the runners #. im a little concerned with moving the builds to the ghcr we might start encountering more issues on that end like we saw with the runners? just a thought

curious about the catalog repo also would that not need changes also now when this comes in?

I think we need to do something about our default Porch "canned" download being in the Nephio catalog repo but I don't think it should be on this PR. I have added a new issue for this, see: kptdev/kpt#4495
