docs: Scans the description text for instances of markdown code blocks flagged
  as `"glimmer"` syntax. If any such instances are found, they are copied,
  stripped of their triple backticks and re-inserted into the
  `templateString` immediately after the original declaration. This allows
  for functional copies of your code examples to be automatically rendered
  into the description, without having to duplicate the code block itself.
  
  If your functional code needs to have different setup to work correctly in
  the Fountainhead context (for example, if you need to use `core-state` to
  set up sandboxed state and controls), simply use `"handlebars"` or no
  syntax flag, and manually add the code block you want Fountainhead to
  render after your example. Neato!
