feat(constants.lua): add typst and ojs comment symbols for code-annotations

[mcanouil]

Introduce comment symbols for the Typst and OJS languages for the code annotations feature.

In addition languages are now sorted to make it easier to see/find the languages.

I've added a test for all 49 languages defined in constants.lua.
Note that all supported languages do not necessarily have proper code highlighting but that does not block the code-annotation feature to work.

---

Context: Writing a blog post with Typst code blocks and had to use # which is not Typst comment symbol.

The document below should work, especially since Typst s embedded in Quarto.

---
format: html
code-annotations: true
---

```{.typst filename="Typst"}
#let my-badge(content, colour: "neutral") = { // <1>
  box( // <2>
    fill: luma(230), // <3>
    radius: 4pt,
    inset: 0.25em,
    text(size: 0.85em, content)
  )
}
```

1. Function definition with content parameter and optional named parameter.
2. [`box`](https://typst.app/docs/reference/layout/box/) creates an inline container.
3. [`luma`](https://typst.app/docs/reference/visualize/color/#definitions-luma) creates a greyscale colour (0-255).
