Log Message:
py-dateutil: update to 2.9.0.0.0.0.

Version 2.9.0.post0 (2024-03-01)
================================

Bugfixes
--------

- Pinned ``setuptools_scm`` to ``<8``, which should make the generated \ 
``_version.py`` file compatible with all supported versions of Python.

Version 2.9.0 (2024-02-29)
==========================

Data updates
------------

- Updated tzdata version to 2024a. (gh pr #1342)

Features
--------

- Made all ``dateutil`` submodules lazily imported using `PEP 562
  <https://www.python.org/dev/peps/pep-0562/>`_. On Python 3.7+, things like
  ``import dateutil; dateutil.tz.gettz("America/New_York")`` will now work
  without explicitly importing ``dateutil.tz``, with the import occurring behind
  the scenes on first use. The old behavior remains on Python 3.6 and earlier.
  Fixed by Orson Adams. (gh issue #771, gh pr #1007)

Bugfixes
--------

- Removed a call to ``datetime.utcfromtimestamp``, which is deprecated as of \ 
Python 3.12. Reported by Hugo van Kemenade (gh pr #1284), fixed by Thomas \ 
Grainger (gh pr #1285).

Documentation changes
---------------------

- Added note into docs and tests where relativedelta would return last day of \ 
the month
  only if the same day on a different month resolves to a date that doesn't exist.
  Reported by @hawkEye-01 (gh issue #1167). Fixed by @Mifrill (gh pr #1168)
