Thanks @blackboxsw. I have one comment / request but looks good to me.

Do we have an external reference (URI) that we could add as a comment above these lists? I'm unsure how to validate this, but I assume you checked it.

I've added the comment:
# Use Azure CLI for valid images: az vm image list -p Canonical --all -o table and the publish image list is what I validated against. I also added back a missing questing release to this PR and I'm following up with drops for unsupported interim release images which are no longer offered on Azure.
