Log where we pull images from in an e2e test

[dims]

/kind cleanup

In this PR, we just run docker images or ctr images list to dump all the image info

At some point we will be making changes to the repository from where we pick up images. We already have a way to inject the location of images for the conformance tests etc, So this will make it easy to eyeball if we are using the correct repositories for each image.
