Update GitHub Actions configuration

Update the GitHub Actions configuration to match the current
fastapi_safir_app template (with some changes that are still pending
review). Stop testing with a matrix of Python versions, since services
need only support one version. Stop using neophile and instead run
make update-deps directly. Use the new tox requirements file instead
of manually listing plugins. Use an environment variable to hold the
Python version so that it can be changed in fewer places. Fix the way
errors from the periodic CI job are reported to avoid a discouraged
GitHub Actions construction.
