Running on Docker throws error

When I try to...

```sh
cd koop
docker build -t koop .
docker run koop
```

I get an error:

```sh
node:internal/modules/cjs/loader:1031
  throw err;
  ^

Error: Cannot find module '@koopjs/koop-core'
}
```

Is it possible the `Dockerfile` wasn't updated after the monorepo refactor?
