Build on multiple architectures

[rickardp]

Currently, no ARM64 images are built. This changes the build script so that ARM64 as well as AMD64 images are built.

Disclaimer: This repo is using CircleCI instead of Github Actions to build, so I cannot test this except locally.

Fixes #7

Will this be resolved some day?

Would be nice to have this as ARM becomes more and more popular in both desktop and cloud environments.

Create a new PR with the same changes? I would offer to create one.

Apologies for the tardiness, I somehow managed to lose the notifications for this one. Great to see it fixed finally!
