[Docusaurus] {=mdx} code block seems broken (Quarto 1.4 with Docusaurus v3) #8333
Description
Bug description
If we use mdx in mdx files, it doesn't seem necessary to write it as code blocks.
``` mdx-code-block should be changed to ```mdx-code-block
Steps to reproduce
---
title: foo
format: docusaurus-md
---
```{=mdx}
export const Highlight = ({children, color}) => (
<span
style={{
backgroundColor: color,
borderRadius: '2px',
color: '#fff',
padding: '0.2rem',
}}>
{children}
</span>
);
<Highlight color="#25c2a0">Docusaurus GREEN</Highlight> and <Highlight color="#1877F2">Rams blue</Highlight> are my favorite colors.
I can write **Markdown** alongside my _JSX_!
```Expected behavior
---
title: foo
format: docusaurus-md
---
```mdx-code-block
export const Highlight = ({children, color}) => (
<span
style={{
backgroundColor: color,
borderRadius: '2px',
color: '#fff',
padding: '0.2rem',
}}>
{children}
</span>
);
<Highlight color="#25c2a0">Docusaurus GREEN</Highlight> and <Highlight color="#1877F2">Rams blue</Highlight> are my favorite colors.
