gcrane: images in gcr.io/go-containerregistry/gcrane have errors and become unusable

[chizhg]

Describe the bug

The images in gcr.io/go-containerregistry/gcrane were updated yesterday and are not usable as before now

To Reproduce

docker pull gcr.io/go-containerregistry/gcrane@sha256:f5439b41bf9909ecb413b40ebb10a9f4884bd0c82e61e415a5bcb588133e4936
gcr.io/go-containerregistry/gcrane@sha256:f5439b41bf9909ecb413b40ebb10a9f4884bd0c82e61e415a5bcb588133e4936: Pulling from go-containerregistry/gcrane
c98c7b4b8e5c: Extracting [==================================================>] 19.31kB/19.31kB
failed to register layer: Error processing tar file(exit status 1): archive/tar: invalid tar header

Expected behavior

Should be able to successfully pull the image

Additional context

Even though I was able to pull it with certain digest, e.g. docker pull gcr.io/go-containerregistry/gcrane@sha256:b04595f709812091b9f55059bce5bf05ef6c9869b677753b7c817167a0105368, running the command got exec /ko-app/gcrane: exec format error

Apparently all the tags but latest and debug have disappeared from the registry. Same goes for gcr.io/go-containerregistry/crane/debug

[max-wittig]

We switched to skopeo. It does the same job of copying images from one registry to the next.
