python-django6 fails to build with Python 3.15.0b2.

version is handled as a special case

For our attempts to build python-django6 with Python 3.15, see:
https://koji.fedoraproject.org/koji/search?terms=python-django6&type=package&match=exact

Let us know here if you have any questions.

Python 3.15 is planned to be included in Fedora 45.
To make that update smoother, we're building Fedora packages with all pre-releases of Python 3.15.
A build failure prevents us from testing all dependent packages (transitive [Build]Requires),
so if this package is required a lot, it's important for us to get it fixed soon.

We'd appreciate help from the people who know this package best,
but if you don't want to work on this now, let us know so we can try to work around it on our side.
