Dockerfile is not multi-arch .

Reason - Base image [docker.io/minio/minio:RELEASE.2021-06-17T00-10-46Z.hotfix.35a0912ff] is only amd64 compliant & need to be multi-arch.

It used to work , if we use base image quay.io/minio/minio:RELEASE.2023-10-16T04-13-43Z as minio-examples
so should i raise PR & update the base image with the above one
@ckadner Can you please provide your input on it
