py-pikepdf: updated to 9.5.2

v9.5.2

- Fixed an issue where temporary files could be left behind when using
  allow_overwriting_input=True and a SIGINT is sent while the file is being
  flushed to disk, or generally within a specific timing window.
- Fixed an issue via OCRmyPDF by replacing an invalid Document Info dictionary
  with a valid dictionary.
