docs: Formats an Object of results.
  
  The Object should be of the same form as the result of
  calling #validate, as the formatter expects the values
  to be piped straight through.
  
  @param results our Object containing validation results.
  @returns {{dependencies: Array, devDependencies: Array}}.
