docs: Sets the `directories` to be blacklisted. Blacklisted directories will
          not be returned or searched recursively when calling
          `collect_directories`.
  
          This will replace the previously stored set of blacklisted
          paths.
  
          `directories` may be a single instance or an iterable. Recommend
          passing in absolute paths. Method will try to convert to absolute path
          based on current working directory.
