Provide ready-to-use Docker images

It would be great to be able to configure and start up a gateway by just running docker pull with prebuilt images.

I brought this up in an issue on the old gateway repo here

This would be especially helpful for projects that want to include a gateway setup in their own docker-compose.yml and do not want to include a dependency on the Vartex repo that would have to exist outside of the working directory or as a Git submodule.

I'm not sure it will work really well to offer standalone docker images, as we are slowly learning the hard way that the cpu and network requirements are too low for a single docker container. So it could just as well be we'd support helm packages rather than docker.

In any case does this command work until we make a decision on path forward?
docker build https://github.com/ArweaveTeam/vartex.git

Interesting. That seems like it should work. It looks like I can use Git URLs with Docker Compose configurations. I'll use this in the meantime, thank you.
