tox-dev/tox-ini-fmt

AI Summary: The task is to modify the `tox-ini-fmt` tool to improve its sorting of Python environments in the `envlist` section of `tox.ini` files. Currently, free-threaded Python versions (e.g., `py314t`) are placed after their vanilla counterparts (e.g., `py314`). The goal is to change the sorting algorithm to keep free-threaded variants next to their corresponding vanilla versions, maintaining numerical order (e.g., `py314, py314t, py313, py313t`, etc.).
