docs: Get Bug suggestions for a given TextLogError (err).
  
      Tries to extract a search term from a clean version of the given error's
      line.  We build a search term from the cleaned line and use that to search
      for bugs.  Returns a dictionary with the cleaned line, the generated search
      term, and any bugs found with said search term.
