[FEATURE_REQUEST] arm64 Docker image

[metawave]

Description of the problem/feature request
I use the docker image on a Ampere machine which uses arm64 arch. It would be much appreciated to also build an arm64 docker image. Binaries seems to work already. With the rise of new ARM based Windows machines (Surfaces) and the already growing Apple Silicon Macs it would make sense to support both.

We are also using arm machines to run GH actions. We would appreciate it if the arm64 build was supported.

Would you like to contribute a patch for this. We are using goreleaser and it supports multiarch builds https://goreleaser.com/cookbooks/multi-platform-docker-images/

We need to create a -arm64 release like it's done for amd
