Import do not work when using workspaces

[Here's an example](https://codesandbox.io/p/devbox/c63ynj?file=%2Fsrc%2Fapp%2Findex.js%3A8%2C15)

Step to reproduce:

```
yarn
yarn start
```

I see that the Readme says: `node_modules are excluded because it's problematic to try to bundle them`. But what about workspaces? I have a separate workspace with configuration files in ts format. Relative import works in this case (../shared-workspace/config), but not by package name (@app/shared-workspace/config).
