Using custom and built-in light and dark highlight-style:

Description

Hi quarto devs

I recently found that when intending to specify both a light and dark highlight-style it's currently required to have both stored locally. Regardless of whether both are built-in or one of them is custom. Wouldn’t it be nice to allow users to choose two different syntax highlight style themes for light and dark mode without having to copy and paste and store locally!?

In case you wondered, yes, I am fully aware that if a built-in theme has both, a light and dark version, we automatically switch (which is great so far of course).

The most related issue I could find was #990.

Here is a .qmd reprex.

This works as expected:

---
title: "Title"
theme: 
  dark: darkly
  light: sketchy
highlight-style: arrow
---

# Header

```{r}
library(purrr)

safe_log <- safely(log, otherwise = NA_real_)

list("a", 10, 100) |>
  map(safe_log) |>
  transpose() |>
  simplify_all()
```

Replacing the YAML with for example what is shown next breaks syntax highlighting:

---
title: "Title"
theme: 
  dark: darkly
  light: sketchy
highlight-style:
  light: a11y-light
  dark: nord
---

If we go to https://github.com/quarto-dev/quarto-cli/tree/main/src/resources/pandoc/highlight-styles and make the files mentioned available locally, it works like so:

---
title: "Title"
theme: 
  dark: darkly
  light: sketchy
highlight-style:
  light: "a11y-light.theme"
  dark: "nord.theme"
---
