ubuntu-latestnow resolves to ubuntu-26.04.actions/setup-pythonhas no Python 3.8 or 3.9 builds for 26.04 (per theactions/python-versionsmanifest; 3.10–3.12 do have them), so the test matrix fails on those versions.This pins the test job to
ubuntu-24.04, which has builds for every version in the matrix (3.8–3.12).publish.ymluses3.xand is unaffected.Note: this is a stopgap. When the 24.04 runner image is retired, either drop EOL Pythons from the matrix or run jobs in
python:<version>containers.Open PRs need to rebase or merge master to pick this up.
