Sync create-django-project with the updated tutorial

[realpython-bot]

Companion sync for the maintenance update of How to Create a Django Project.

• Draft article: https://realpython.com/pbjt/blog/post/2404/change/
• Maintenance card: https://trello.com/c/mYpmufjA

What changed

The tutorial now targets Django 6.1 (PyPI current: 6.1.1), so the folder is synced to what a reader gets today:

• requirements.txt re-pinned to django==6.1.1, asgiref==3.12.1, sqlparse==0.6.0.
• pyproject.toml dependency bumped to django>=6.1.
• settings.py, urls.py, asgi.py, wsgi.py: generated docs links moved from en/6.0/ to en/6.1/, and the settings header now names Django 6.1.1.
• settings.py gains the MAILERS block that django-admin startproject emits on Django 6.1, written in the folder's existing double-quote style.

The hand-applied house style in the folder (double quotes, # noqa: F401 markers, wrapped SECRET_KEY) is preserved — only the 6.0 -> 6.1 scaffolding deltas were applied, not a wholesale regeneration.

Verification

• Fresh Python 3.12 virtual environment installed from the new requirements.txt (Django reports 6.1.1).
• python manage.py check -> no issues; python manage.py migrate -> all migrations applied.
• python manage.py runserver smoke test -> GET /admin/login/ returns HTTP 200.
• Repo gates with the pinned ruff 0.14.1: ruff format --check (12 files already formatted) and ruff check both pass.
