Migration for Quay/Dockerhub automated builds to GitHub Actions was done earlier today.
I'll need to redesign the dockerfile slightly and add some logic to it to detect which CPU Arch its running on (ARMv7, ARMv8, AMD64, etc) and adjust the make flags accordingly in order to support multi-arch builds

In addition to the slight redesign, rblaine95/dockerhub-mirror#1 will need to be solved, unless I drop Quay entirely
