Sync celery-async-tasks with the updated tutorial

Maintenance update for Asynchronous Tasks With Django and Celery.

What changed

Both source_code_initial/requirements.txt and source_code_final/requirements.txt get the same fresh pins, matching the article's updated dependencies field and its pinned install commands:

• Django 5.1.3 -> 6.1.1
• celery 5.4.0 -> 5.6.3
• redis (redis-py) 5.2.0 -> 8.1.0
• Transitive pins re-resolved from the same install: amqp 5.4.0, asgiref 3.12.1, billiard 4.3.0, kombu 5.6.2, click 8.5.0, and others. packaging, typing_extensions, and tzlocal are new transitive dependencies.

Why: Django 5.1 is end-of-life and doesn't officially support Python 3.14. The article now tells readers to install django==6.1.1, celery==5.6.3, and redis==8.1.0, so the downloadable project should match. The code files already match the article, so no code changes were needed.

README.md now covers Linux as well as macOS. It adds the apt command for Redis next to Homebrew, notes that Django 6.1 needs Python 3.12 or newer and that Celery doesn't support Windows, and spells out the http:// dev server URL. These match the article's Linux and macOS install tabs.

Verification

• Fresh Python 3.14.7 venv, pip install -r source_code_final/requirements.txt, pip check clean, manage.py check clean, migrate OK.

• With Redis 7.0.15 running, the Celery worker connected to redis://localhost:6379//. A form POST returned 302 in 0.16 s, and send_feedback_email_task succeeded in 20.01 s in the worker.

• The full article learner path, from source_code_initial to the final state, was run on the same versions during the article update.
