docs: Return zipimporter cache entry keys related to a given normalized path.
  
      Alternative path spellings (e.g. those using different character case or
      those using alternative path separators) related to the same path are
      included. Any sub-path entries are included as well, i.e. those
      corresponding to zip archives embedded in other zip archives.
