Add ARM64 docker build

[reqlez]

ARM64 is widely used nowadays, so this PR covers ARM64 users:

• Modify Dockerfile to add sbt image that supports arm64
• Change docker publish GH action to build and publish arm64 image.

Personally, I run eclipse temurin jre everywhere, however, you are welcome to change it if this is not what you prefer.

Hi @reqlez this code is about to be removed as I changed from Cassandra to simply just a JVM process. Also it needs a stronger machine to synchronize so I believe ARM64 is not really suitable at all for an explorer, so even if I managed to keep it, it would be just a risk of switching from a well tested docker image. There are more factors like Java version, etc. This is really "thin ice" area )) Sorry

My ARM64 machines are faster than a lot of AMD machines out there, are you thinking that the only people that use ARM64 are Raspberry Pi users LOL I run production grade servers on ARM64 all the time.

Also, I switched the Ergo node repo to that image, and nobody complained ;-)

But up to you, this is your repo, of course. If you don't feel it's necessary, don't merge, however, I will be running this explorer on ARM64 anyways :P

PS: I really have "beef" with developers not adding arm64 support to their repos, like arm64 does not exist. All major datacentres now have ARM64 servers, and ARM64 is really taking over the datacentre market these days. So you will have to forgive me, when I feel that the excuses people provide not to add arm64 are mostly anecdotal evidence.

I'm just going to leave this link here as well: https://www.ipi.wiki/products/ampere-altra-developer-platform?variant=42970872086690

I have absolutely no time to make the old docker infrastructure work and test it so accepting your PR would most likely mean that somewhen in December I will hit some strange error originating from using different docker image and java version and will have no clue what is going on.

Let's have it open, thanks @reqlez

I hope you will consider adding arm64 support in the near future, thank you!

If you ever need any docker/infrastructure help, I have a bit of experience in that, so please don't be shy, always happy to help a fellow Ergo community member.
