bad architecture metadata in k8s.gcr.io images

[paleozogt]

What happened:

While thek8s.gcr.io/metrics-server/metrics-server images are multi-arch, the architecture metadata in each image is incorrect.

For example, all the images have amd64 as their architecture:

$ docker pull --platform linux/arm64/v8 k8s.gcr.io/metrics-server/metrics-server:v0.5.1
$ docker inspect k8s.gcr.io/metrics-server/metrics-server:v0.5.1 | grep Arch
        "Architecture": "amd64",

$ docker pull --platform linux/ppc64le k8s.gcr.io/metrics-server/metrics-server:v0.5.1
$ docker inspect k8s.gcr.io/metrics-server/metrics-server:v0.5.1 | grep Arch
        "Architecture": "amd64",

Contrast this to how other images behave:

$ docker pull --platform linux/arm64/v8 k8s.gcr.io/pause:3.5
$ docker inspect k8s.gcr.io/pause:3.5 | grep Arch
        "Architecture": "arm64",

$ docker pull --platform linux/ppc64le k8s.gcr.io/pause:3.5
$ docker inspect k8s.gcr.io/pause:3.5 | grep Arch
        "Architecture": "ppc64le",

What you expected to happen:

The architecture metadata for an image should match its entry in a multi-arch manifest.

Anything else we need to know?:

I haven't checked other images on k8s.gcr.io, but it may be that there are others with this same mistake.
