Add arm64 support for docker image

[tamasbakos]

Could you please create a docker image that will run on a Raspberry Pi 4 as well (platform linux/arm64/v8 ) ?
I saw here that currently there is only a docker image for platform linux/amd64 .

The steps for creating a multi platform image can be found here:
