v1.40.0: A3 Mega and A3 High families supported in GKE

[tpdownes]

What's Changed

Important

All HPC VM images based upon CentOS 7 have been deprecated. This means that
referring to the "hpc-centos-7" family in the "cloud-hpc-image-public"
project will fail. We recommend migrating to the "hpc-rocky-linux-8" family
that is the new default throughout the Toolkit. If CentOS 7 is truly needed,
the final HPC CentOS 7 image can be used by its name: "hpc-centos-7-v20240712".
