type SandboxBoxNewSnapshotParamsImageConfig structImageConfig sets the command and ports the snapshot records, as a Docker image's ENTRYPOINT, CMD and EXPOSE do. By default a capture keeps those of the snapshot the sandbox was created from; each field given here replaces that one, and an empty list clears it. A function serving the snapshot runs this command and listens on its one exposed port.
