Hidelines does not work with multiple languages

[Mouthless-Stoat]

Problem

output.html.code.hidelines does not seem to work with any other language apart from the example language python and rust. I have try json, gdscript and none of the language work

Steps

1. Create a new book
2. In the book.toml add:

   [output.html.code.hidelines]
   json= "~"

3. Edit a chapter and add

   ```json
   {
   ~"hello"
   }
   ```

4. Render the page using mdbook serve and see the code block not render with hidden lines.

Hm, I'm not able to reproduce with the given example. Can you check if there are any errors in the javascript console? Can you check if the generated HTML code block has <span class="boring">?

After messing around some more seem to be my version of highlight.js being weird. It seem downloading a custom build of highlight.js cause some issue idk if this is more highlight.js issue or more of mdbook issue:

All I did was go to the custom build site and select only json download that and copy over the highlight.min.js file into the theme/highlight.js file. While I'm here how do i acctually add a new 3rd party language to highlight.js

The newer versions of highlight.js won't work. There are instructions at https://github.com/rust-lang/mdBook/blob/master/CONTRIBUTING.md#updating-highlightjs for checking out an older version and building it. We're currently on 10.1.1.
