Docker builds for Linux ARM64

[SkyfallWasTaken]

It would be great if there were Docker builds for Linux ARM64, so folks with ARM servers can use Fizzy!

For some not explained reason the arm image build was disabled: #1804

Coolify just added the service and usually coolify runs on raspberry, so a arm build/image would be awesome!

I've asked over in #1804 to see if we can get some context as to why arm builds were disabled: #1804 (comment)

I was hoping to deploy onto a Raspberry Pi.

If we get any information on what is blocking then the community can help get it to a state where it can be readded. As it is, we're working blind since it all seems to be working fine. I have plenty of docker experience but image architecture is one thing I haven't messed with. I threw it to Cursor to see if it could build it for Apple Silicon in a way that I can verify. It came up with a test script here that others can try: https://github.com/dakotahp/fizzy/pull/1/changes#diff-b817a03f9af94fd5122c29a8e8eda20f4bfb6550a3f7e07d7d3272bd8908fd8f

The gist is that the Dockerfile already is set up for dynamic architecture, and the bundle process works fine for me. I didn't experience any ruby gem failures to compile. That said, it is possible that maybe the dockerfile is picking up on the gems being bundled locally on my machine prior to trying to build the Dockerfile.

Any other things that sound actionable to anyone for next steps?

For now you can use this snippet to build it during deployment:

services:
  fizzy:
    build:
      context: 'https://github.com/basecamp/fizzy.git#main'
      dockerfile: Dockerfile
    environment:
....

This will pull the repository and use the original docker file to build on your arm64 with success!
