Feature Request: syntax highlighting of code blocks

It would be amazing if markdown fenced code blocks supported syntax highlighting throughout the UI, such as in the tabs [Readme], [Inputs], [Outputs], etc. The [Usage] field uses syntax highlighting on the generated terraform. Using the same rules in other places would be great.

As a bonus, supporting syntax highlighting of not only terraform code, but other types of code that might be commonly encountered in terraform would be useful as well. Languages and/or formats such as YAML, JSON, python, javascript, etc.
