py-lxml: updated to 4.9.4

4.9.4 (2023-12-19)
==================

Bugs fixed
----------

* Inserting/replacing an ancestor into a node's children could loop indefinitely.

* ``TreeBuilder.close()`` could fail with a ``TypeError`` after
  parsing incorrect input.  Original patch by Enrico Minack.

* A file-system specific test is now optional and should no longer fail
  on systems that don't support it.

Other changes
-------------

* Wheels include zlib 1.3, libxml2 2.10.3 and libxslt 1.1.39
  (zlib 1.2.12, libxml2 2.10.3 and libxslt 1.1.37 on Windows).

* Built with Cython 0.29.37.
