Long inline `<code>` snippets within lists do not wrap (HTML documents)

Bug description

This is similar to these old issues about inline <code> not wrapping: https://github.com/quarto-dev/quarto-cli/issues/2649, https://github.com/quarto-dev/quarto-cli/issues/3221

Those two issues are fixed, but there seems to be another edge case with inline <code> not wrapping if it's inside a list. Outside of lists, <code> gets white-space: pre-wrap styling that wraps the text. Within lists, <code> gets white-space: pre styling that does not wrap.

We found this CSS that sets pre-wrap on code only if code is inside a <p>, which doesn't happen for code within lists.

https://github.com/quarto-dev/quarto-cli/blob/c6987f7156e5de96da78cf5be281fc64689b7333/src/resources/formats/html/_quarto-rules.scss#L289-L294

It's a really minor issue, but I think you could hit this in some common cases. We discovered it in the Posit Package Manager release notes, where we have lists of changes that occasionally contain long inline error messages wrapped in code. The release notes have a sidebar that limit the width of the content, so we had a few occurrences of this.

We also worked around it by separating each list item with a newline, which gets each list item wrapped in a <p>. But this is somewhat of an awkward workaround.

Steps to reproduce

Repro doc:

---
title: "Test for text wrapping of long inline `<code>` snippets in lists"
---

## Unordered list

Unordered list. `<code>` within lists gets `white-space: pre` styling which does not wrap.

- `Code 1`
- `Code 2`
- `This is a really long inline code snippet. This is a really long inline code snippet. This is a really long inline code snippet. This is a really long inline code snippet. This is a really long inline code snippet. This is a really long inline code snippet. This is a really long inline code snippet. This is a really long inline code snippet. This is a really long inline code snippet. This is a really long inline code snippet. This is a really long inline code snippet. This is a really long inline code snippet. This is a really long inline code snippet. This is a really long inline code snippet. This is a really long inline code snippet. This is a really long inline code snippet. This is a really long inline code snippet.`
- Item 4


## Unordered list with line breaks (workaround)

Unordered list with line breaks. Each item gets wrapped in `<p>` which matches the `white-space: pre-wrap` CSS. This works around the issue, but the extra space between list items can be awkward.

- `Code 1`

- `Code 2`

- `This is a really long inline code snippet. This is a really long inline code snippet. This is a really long inline code snippet. This is a really long inline code snippet. This is a really long inline code snippet. This is a really long inline code snippet. This is a really long inline code snippet. This is a really long inline code snippet. This is a really long inline code snippet. This is a really long inline code snippet. This is a really long inline code snippet. This is a really long inline code snippet. This is a really long inline code snippet. This is a really long inline code snippet. This is a really long inline code snippet. This is a really long inline code snippet. This is a really long inline code snippet.`

- Item 4

## Ordered list

Ordered list:

1. `Code 1`
2. `Code 2`
3. `This is a really long inline code snippet. This is a really long inline code snippet. This is a really long inline code snippet. This is a really long inline code snippet. This is a really long inline code snippet. This is a really long inline code snippet. This is a really long inline code snippet. This is a really long inline code snippet. This is a really long inline code snippet. This is a really long inline code snippet. This is a really long inline code snippet. This is a really long inline code snippet. This is a really long inline code snippet. This is a really long inline code snippet. This is a really long inline code snippet. This is a really long inline code snippet. This is a really long inline code snippet.`
4. Item 

## Inline code by itself

Outside of lists, this gets wrapped in `<p>` so it gets the `white-space: pre-wrap` CSS.

`This is a really long inline code snippet. This is a really long inline code snippet. This is a really long inline code snippet. This is a really long inline code snippet. This is a really long inline code snippet. This is a really long inline code snippet. This is a really long inline code snippet. This is a really long inline code snippet. This is a really long inline code snippet. This is a really long inline code snippet. This is a really long inline code snippet. This is a really long inline code snippet. This is a really long inline code snippet. This is a really long inline code snippet. This is a really long inline code snippet. This is a really long inline code snippet. This is a really long inline code snippet.`

Actual behavior

The inline code items do not wrap in the Unordered list and Ordered list cases.

Expected behavior

The inline code items wrap in the Unordered list and Ordered list cases.

Start with src/resources/formats/html/_quarto-rules.scss at lines 289-294, then render the supplied Quarto reproduction document. Compare long inline code in ordered and unordered lists with the paragraph case, and verify that the list examples wrap in the generated HTML output without relying on the newline workaround.
