py-html-sanitizer: updated to 2.4.4

Next version

- **Vulnerability:** Fixed an issue where normalizing unicode too late in the
  process would keep disallowed tags when using specially crafted HTML. Fixed
  in 2.4.2.
- Fixed missing whitespace while merging adjacent tags.

2.4 (2024-04-01)

- Fixed an edge case where ``br`` tag attributes weren't removed if the br tag
  appears first.
- Updated the ``lxml`` dependency to 5.2 and added the now-required
  ``lxml[html_clean]`` extra.
