external_auth_windows task fails on windows-2016-dc - missing Python 3.13

Problem

The external_auth_windows task fails during venv setup because windows-2016-dc distro only has Python 3.10 installed, but prelude_python.sh now expects Python 3.13.

which: no python.exe in (/cygdrive/c/python/python313)
Command 'subprocess.exec' ('adjust venv') failed: exit code 1

Affected Tasks
