### Bug description

Hello,

Thanks for making quarto, it's super cool 😄 

If I embed a Jupyter cell as described here:

https://quarto.org/docs/authoring/notebook-embed.html

in a small document `test.qmd`:

```
---
title: Exploration of penguin characteristics
author: Norah Jones
toc: true
format:
  html:
    code-fold: true
---

# Embedded report

{{< embed penguins.ipynb  >}}
```

and render the document with:

```
$ quarto render test.qmd --to html --execute --no-cache -o test.html
```

The code in the embedded Jupyter notebook isn't evaluated. 

This isn't what I expect with the `--execute` flag. Instead, to update the Jupyter cell content dynamically I have to run:

```
$ jupyter nbconvert --to notebook --inplace --execute penguins.ipynb
$ quarto render test.qmd --to html --execute --no-cache -o test.html
```

I'm not sure if this is expected behaviour, but it took me a little while to figure out.

Thanks!
