python3.13: use sys.executable instead of removed Py_GetProgramFullPath
According to
https://docs.python.org/3.13/c-api/init.html#c.Py_GetProgramFullPath,
it’s only deprecated, but not removed. Do you have other information?
I could not make it work with the PyConfig API from the extension. But fetching
sys.executable seems to work fine and isn't that verbose.
I think the PyConfig struct memory is released after interpreter
initialization, so I think PyConfig is out of question anyway.
https://docs.python.org/3.13/c-api/init.html#c.Py_GetProgramFullPath
suggests sys.executable as the alternative, so feel to change the patch
description to be more bold. :)
