code syntax highlighting

[alexguja]

It seems like changing the theme of the site doesn't have much effect on the code syntax highlight.
For instance, when selecting the Ayu theme, the code theme defaults to a different theme.

See below.
It seems like the code theme is Coal, but it should be Ayu.

Hello, feel free to help us open a PR to that! ❤️

Hey Mario,

I did some digging and it seems like the issue comes from this line in mdBook

ace_theme = "ace/theme/tomorrow_night"; should probably say
ace_theme = "ace/theme/ayu_highlight";

However, it seems like the ayu theme is missing from the ace themes

For reference, I found a related issue in the mdBook repo

I am not entirely sure how mdBook works just yet, so if nobody beats me to it I'll try to open a PR
