Dockerize

Not sure if this is desired or not, so tossing it out there:

• added a Dockerfile setup, and CI to build it on each push to main branch to enable a quick setup and run of the automerge-repo-sync-server codebase for integration testing
• updated the sync server to the current latest automerge-repo release
• tossed some quick notes into the README for how to invoke it

Thanks for this! It would be great if this repo provided a Docker image that Just Worked for basic demo/testing needs.

If you'd like something immediately, you're more than welcome to pull from https://github.com/heckj/automerge-repo-sync-server and the package there. Not guaranteed to be as up to date as this, but I was using it in testing the Swift language variant of automerge-repo for interoperability verification.
