python3-pyparsing: upgrade 3.2.3 -> 3.2.4

Release notes (https://github.com/pyparsing/pyparsing/releases):

- Barring any catastrophic bugs in this release, this will be the last
  release in the 3.2.x line. The next release, 3.3.0, will begin
  emitting DeprecationWarnings when the pre-PEP8 methods are used (see
  header notes above for more information, including available
  automation for converting any existing code using pyparsing with the
  old names).
- Fixed bug when using a copy of a Word expression (either by using the
  explicit copy() method, or attaching a results name), and setting a
  new expression name, a raised ParseException still used the original
  expression name. Also affected Regex expressions with as_match or
  as_group_list = True. Reported by Waqas Ilyas, in Issue #612 - good
  catch!
- Fixed type annotation for replace_with, to accept Any type. Fixes
  Issue #602, reported by esquonk.
- Added locking around potential race condition in
  ParserElement.reset_cache, as well as other cache-related methods.
  Fixes Issue #604, reported by CarlosDescalziIM.
- Substantial update to docstrings and doc generation in preparation for
  3.3.0, great effort by FeRD, thanks!
- Notable addition by FeRD to convert docstring examples to work with
  doctest! This was long overdue, thanks so much!
