Subject: [PATCH] Pass KAMAL_VERSION env var to container run

In lieu of a general purpose mechanism to pass dynamically-evaluated env-vars at container execution time, we can pass the `config.version` as KAMAL_VERSION to avoid having to take apart the container name just to determine the SHA of the deployed version in the entrypoint.
