Add support for ARM 64

[tuzzmaniandevil]

Describe the solution you'd like
Support for Raspberry PI's, I'm using a Pi 4 running the 64-bit OS, Support for ARM 64 would allow me to run this on my Pi Cluster. Java 8 is already support as you can see Here

Describe alternatives you've considered
I used to run this image on a standard PC until the motherboard died to thought I would try out a Pi Cluster instead.

👋 - Hello!

That's a fun one. I haven't setup ARM images before, but it's certainly do-able with the infrastructure out there. I'll look into it!

I would be glad having an arm64 docker image, too.

I've done such thing already here maybe you can copy it... https://github.com/pietmacom/cups2mqtt/tree/main/.github/workflows
