Decode character entities given in descriptions.

[toddjordan]

This is a patch for emberjs/ember.js#18063 which lets us provide yuidoc special characters as html character code entities and decodes them before we apply highlightjs and markdown processing.

Here's a preview of the screen for the above issue

Waiting for @sivakumar-kailasam to chime in before we merge this

This is exactly what I had in mind.🙏 @toddjordan could you make the test pass before merging this though?

[toddjordan]

@sivakumar-kailasam so husky was preventing the build from passing because it was adjusting the indentation of a switch statement in the file, so for now I'm removing husky so we can get this in.

[toddjordan]

if someone has a husky config that plays well with our eslint config we can re-enable it
