Yeah, the highlighter we use doesn't have any built-in styling for YAML. I
had to search around quite a bit for context and came up mostly dry.
Moreover, the actual tokenizer it uses only emits two token types,
l-Scalar-Plain and p-Indicator. (You can see this in action by inspecting the
HTML
[here](https://ci.apache.org/projects/flink/flink-docs-release-1.2/monitoring/metrics.html#jmx-orgapacheflinkmetricsjmxjmxreporter))
This change applies the color I found most applicable from the existing
highlighting rules and applies it to l-Scalar-Plain to make it at least
slightly more interesting than black-on-white.
