* Dockerfile: specified reasonable defaults options for containerized kopia * addressed pr comments, switched to gcr.io/distroless/static:nonroot distroless has no executable code, so this requires KOPIA_PASSWORD to always be provided via env, b/c distroless does not have /bin/stty to disable TTY echo (we should not require that, BTW) * site: added docker image documentation
