Blockquote pattern

Hi Stephanie, great idea & content! I learned about role='list' on `

`.

I was recently curious about blockquote patterns and it seems that the recommendations have changed and the [WHATWG HTML spec](https://html.spec.whatwg.org/multipage/grouping-content.html#the-blockquote-element) is not recommending `` in `

` anymore, but rather something like:

```html

quote

The issue suggests updating the blockquote pattern in the repository's HTML snippets. Look for existing blockquote examples in the codebase, likely in Nunjucks templates or markdown files. Compare the current implementation with the WHATWG spec's recommended structure using figure, blockquote, and figcaption. Test the updated snippet in a browser to ensure it renders correctly.
