Previously Python 3.9 was only supported on the Heroku-22 stack (Ubuntu 22.04) and older, since it reaches EOL in Oct 2025.
However, support for Python 3.9 on Heroku-24 (Ubuntu 24.04) was just added, by the building/uploading of the binaries in:
heroku/heroku-buildpack-python#1656
As such, the tests need updating to reflect that CNB builds will no longer fail with an unavailable Python error when using Python 3.9 on
heroku/builder:24
