Forwarded request #1156451 from bnavigator

- Update to 2.9.0.post0
* Pinned setuptools_scm to <8, which should make the generated
_version.py file compatible with all supported versions of
Python. (We don't do this at openSUSE, we don't need Python 2
installs from a setuptools_scm v8 build)
- Version 2.9.0
* Updated tzdata version to 2024a. (gh pr #1342)
* Made all dateutil submodules lazily imported using PEP 562. 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)
* 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).
- Provide underscore name: some consuming packages go with that,
don't fail unnecessarily
- Drop no-utcfromtimestamp.patch
