djackets_django build fails on Python 3.12

[Antonio Abella]

The djackets_django Dockerfile specified FROM python:3 which is now 3.12. Build throws errors when installing PyYAML:

7.575 Collecting PyYAML==6.0 (from -r requirements.txt (line 27))
7.610   Downloading PyYAML-6.0.tar.gz (124 kB)

After bumping the PyYAML version in requirements.txt the image builds successfully, but the app fails to run with errors from stripe:

    from order import views
  File "/app/order/views.py", line 1, in <module>
    import stripe

    from stripe.six.moves.urllib.parse import parse_qsl
ModuleNotFoundError: No module named 'stripe.six.moves'

Pinning the Python version to 3.11 in the Dockerfile resolves these issues for the moment.
