python3-django 5.0.11: ignore CVE-2025-27556

Upstream Repository: https://github.com/django/django.git

Bug Details: https://nvd.nist.gov/vuln/detail/CVE-2025-27556
Type: Security Advisory
CVE: CVE-2025-27556
Score: 7.5

Analysis:
- CVE-2025-27556 affects Django 5.1 before 5.1.8 and 5.0 before 5.0.14.
- The issue occurs due to slow NFKC normalization on Windows, which can cause
  a denial-of-service (DoS) when handling inputs containing a very large number
  of Unicode characters.
- Affected Django components:
	django.contrib.auth.views.LoginView
	django.contrib.auth.views.LogoutView
	django.views.i18n.set_language

- This performance degradation is specific to Windows, caused by the Windows
  Unicode normalization implementation.
