Python wheels, pyenv, and a number of other tools use 't' in the Python version number to identify free threaded builds. For example, '3.13t', '3.14.0a1', '3.14t-dev'.
This PR supports that syntax in
actions/setup-python
, strips the "t", and adds "-freethreading" to the architecture to select the correct Python version.See #771 and actions/python-versions#319
