Support for docker arm builds

[PacketCrunch]

Is your feature request related to a problem? Please describe.
Current arm docker release is from a old version. Need arm image from latest source.

Describe the solution you'd like
Probably something integrated with gh-actions would be great, similar to what is done for x86_64 builds.

Additional context
It could be useful for many folks using AWS Graviton or OCI Ampere based systems

Hi this is good feature request, because a lot of people are running their workload on arm based instance nowadays in the cloud or on the edge . please can you provide some instruction ? i wanted to experiment on raspberryPi , and i was surprised by the fact that there is no arm based image , so i couldn't run my test on that hardware .
