No language "yaml" for markdown code snippets

[Moonbase59]

I use the style-sherpa not only for creating the styleguide but also for creating an "info.html" file containg some information for the agency/customer. Since I build heavily parametrized sites, there is almost always some documentation about parameter settings in some src/data/xxx.yml files.

Unfortunately, style-sherpa errors out on

```yaml
```

code blocks.

Since YAML can be heavily used in Foundation projects, it would just be great if the Markdown compiler would support this language for highlighting.

Thanks for considering this!
