### Bug description

There are a few places on the docs website where the code chunk language is not correct. It appears to be a random (?) string of letters instead of the actual language for the code chunk. These are the places where I've seen the problem:

- At [Authoring > Diagrams](https://quarto.org/docs/authoring/diagrams.html#overview)

- At [Authoring > Figures > Cross-references](https://quarto.org/docs/authoring/figures.html#cross-references)
