No minor tags images for arm64v8 could be fetched

[JackLiar]

According to the Docker Hub documentation:

Additionally, images with minor version tags that correspond to install media are also offered. These images DO NOT receive updates as they are intended to match installation iso contents. If you choose to use these images it is highly recommended that you include RUN yum -y update && yum clean all in your Dockerfile, or otherwise address any potential security concerns. To use these images, please specify the minor version tag:

For example: docker pull arm64v8/centos:5.11 or docker pull arm64v8/centos:6.6
