python3-django: upgrade 4.2.20 -> 4.2.27

Upstream has switched from setuptools3 build backend to setuptools_build_meta,
however their setuptools requirements are higher than what's available in oe-core.
As a workaround, add a patch that lowers the requirements. This change has been
tested by successfully executing the django test suite in qemu (without Selenium tests).

Changes:
4.2.27: https://docs.djangoproject.com/en/6.0/releases/4.2.27/
- Fix CVE-2025-13372
- Fix CVE-2025-64460
- Fixed a regression in Django 4.2.26 where DisallowedRedirect was raised by
  HttpResponseRedirect and HttpResponsePermanentRedirect for URLs longer than 2048 characters.
  The limit is now 16384 characters

4.2.26: https://docs.djangoproject.com/en/6.0/releases/4.2.26/
- Fix CVE-2025-64458
- Fix CVE-2025-64459

4.2.25: https://docs.djangoproject.com/en/6.0/releases/4.2.25/

4.2.21: https://docs.djangoproject.com/en/6.0/releases/4.2.21/
- Change build backend
- Fix CVE-2025-32873
- Fixed a data corruption possibility in file_move_safe() when
  allow_overwrite=True, where leftover content from a previously larger file could
  remain after overwriting with a smaller one due to lack of truncation
- Fixed a regression in Django 4.2.20, introduced when fixing CVE 2025-26699,
  where the wordwrap template filter did not preserve empty lines between paragraphs
  after wrapping text
