apacheGH-37993: [CI] Fix conda-integration build (apache#37990)

pitrou · loicalleyne · commit 50b785ca7a83 · 2023-11-13T17:14:48.000-05:00
### Rationale for this change The conda-integration build has recently started failing: https://github.com/apache/arrow/actions/runs/6393852866/job/17353952453 Apparently this is because conda-forge is now providing Python 3.12 by default, and pythonnet [does not support it yet](pythonnet/pythonnet#2249). ### What changes are included in this PR? Avoid using Python 3.12 for Archery in conda-integration build. ### Are these changes tested? Yes, by construction. ### Are there any user-facing changes? No. * Closes: apache#37993 Authored-by: Antoine Pitrou <antoine@python.org> Signed-off-by: Raúl Cumplido <raulcumplido@gmail.com>
