Update the CI actions, test on Python 3.14 and move the publish job to Python 3.13

actions/checkout@v4 and actions/setup-python@v5 run on Node 20, which
GitHub has deprecated on its runners; both move to their current major
versions, which run on Node 24. Python 3.14 joins the test matrix and
the classifiers. The publish job no longer pins the 2022 patch release
3.10.4; it uses 3.13, a version the test matrix covers, and installs
build without --user.
