Finalized linting changes

In the fetch_text method (line ~207):
  if not r.encoding:
      r.encoding = "utf-8"  # ← Double quotes!

  In the scrape method, make sure there are 2 blank lines before the next class:
          return None


  class Tekstowo(SearchBackend):  # ← Two blank lines above

  That should pass the formatting check! The repo follows PEP 8 style (double quotes, 2 blank lines between classes).
