CaseClauseError if component doc contains fenced code block with non elixir/heex lang

[woylie]

If a component documentation contains a fenced code block with a language other than Elixir or HEEx, a CaseClauseError is produced and the story cannot be rendered.

@doc """
Here's some example CSS:

```css
.component {
  color: pink;
}
```-
"""

(Added a dash to trick the GH syntax highlighter.)
