Bug#1076084: cctbx: autopkgtest failure with Python 3.12 only

[Graham Inggs]

Source: cctbx
Version: 2023.12+ds2+~3.17.0+ds1-4
Severity: serious
User: debian-python at lists.debian.org
Usertags: python3.12

Hi Maintainer

cctbx's autopkgtests fail with Python 3.12 as the only supported
version [1].  I've copied what I hope is the relevant part of the log
below.

This should have been detected when Python 3.12 was made the default
version (while 3.11 was still supported), since cctbx builds
extensions for both versions.  However, debian/tests/cctbx and dxtbx
both contain:

py3versions -r

Maybe this needs to be 'py3versions -s' in order to test with both
supported versions.

Regards
Graham
