Publish a docker image when we do a release of this repo about soroban-example-dapp

We can use quickstart as a model for how to set this up, but multi-arch will add a lot of complexity here

Hello. Just to add some info about the alternative:

I was supporting the following repo: https://github.com/esteblock/soroban-preview-docker/
Docker images then published in https://hub.docker.com/repository/docker/esteblock/soroban-preview/general

In the repo each folder will hold a different Preview Dockerfile.
We could also add a github action to publish them

You mean that we can also install soroban-cli in quickstart, and then execute soroban-cli commands inside the quickstart containter? That would be great! Just use one container for all!
