Bug report

Bug description:

The Python 3.10.16 release is missing the GPG signature files (note no "GPG" column in the table):
https://www.python.org/downloads/release/python-31016/

eg:

$ curl -I https://www.python.org/ftp/python/3.10.16/Python-3.10.16.tgz.asc

This is causing our release process for the new binaries to fail, blocking releasing this security update to users:
https://github.com/heroku/heroku-buildpack-python/actions/runs/12159162945/job/33908683580#step:4:19

All of the other releases mentioned in https://blog.python.org/2024/12/python-3131-3128-31111-31016-and-3921.html have their GPG signatures, as does the last Python 3.10.x release (3.10.15).

This seems to be a repeat of #123807.
