Updated highlightjs to v9.0.9

[daemedeor]

Updated the highlight.js library to the v9.0.9 version that allows for more language support like Julia. Also updated the tests as some of the library changes the markup a little, namely with a wrapper. I tested with Chrome only but I don't think that it should have a major effect on the other parts of the library. This is in response to another issue that was brought up a bit ago and since it was quick to do: #402

[daemedeor]

I have to fix it up, since the Mozilla store does not allow minified version of the highlight.js file....

[daemedeor]

Okay, now it's updated to use the non minified version

See #402

[daemedeor]

@ickc this is to solve the request to update it, it's not a issue but it's a PR

[ickc]

I mean to cross reference it to #402, since your original comment has a typo that reference to #403. I was just lazy so I didn't write this (and I see you already corrected your typo)

@adam-p Attached is v9.12.0 with the styles.json updated accordingly.

@adam-p Would you prefer an update to this pr or a new pr instead? This issue is a longstanding one and your extension relies upon highlight.js for syntax highlighting. It would be great to have the extension updated with a newer version of highlight.js which supports more languages.

Kotlin seems not working in the current version, checked https://github.com/adam-p/markdown-here/blob/master/src/common/highlightjs/highlight.js and cannot find registerLanguage for Kotlin also. Is there some else needed to do to support Kotlin?
