### Bug description

````markdown
---
title: "test"
format: docx
---


:::{.callout-caution}
## Running Code

```{r}
1 + 1
```

:::
````

This causes this issue : 
````bash
An error occurred
Found a nested callout in the document. Please fix this issue and try again.
````

This does not happen in PDF and HTML. 

This error is thrown from 
https://github.com/quarto-dev/quarto-cli/blob/852c9bb99e54e0163575ceecf7dde372b4b73321/src/resources/filters/quarto-pre/callout.lua#L533-L538

where we check for nested Divs. 

The Markdown generated by Quarto before Pandoc rendering is the following

````markdown
:::{.callout-caution}
## Running Code


::: {.cell}

```{.r .cell-code}
1 + 1
```

::: {.cell-output .cell-output-stdout}
```
[1] 2
```
:::
:::


:::
````

Hence the error thrown. 

I believe this should be fixed - not sure about the context of nested Divs not allowed in Docx @dragonstyle (https://github.com/quarto-dev/quarto-cli/commit/688fd1c070739e3d629d65773da6760ad1d74e41) but it does seem something we should allow for our own expected div right ?
