aarch64 Docker Image

[jzbor]

Description

It would be nice if there was an official aarch64 image provided alongside the official x86_64 images.

Why it should be implemented

A lot of educational homelab devices (e.g. Raspberry Pi) run on this architecture, but there are also cloud hosts like Hetzner that provide cheap aarch64 boxes.

Seems like it should be as easy as adding a "platform" option to the workflow.

should be fixed by #590

Thanks a lot!
