Reference links edits:

- fix broken normalize() utility in test suite so that it produces
  output that doesn't choke referenceLinks.
- add DocumentationConfig option `--noReferenceLinks` which will be
  **internal only**, and turns off reference links for `readme` mode
- rebuilds test output with these changes

unrelated but minor

- includes .prettierrc and updates calls to prettier to use that instead
  of CLI options
