summary:

Fix PyVectorcall_Function doc versionadded (#107140)

The documentation implies that PyVectorcall_Function() was available in Python 3.8.
This is half-true - it was available under a different name. I think it's clearer to set
the "version added" to 3.9.

    which can be done by checking ``PyVectorcall_Function(op) != NULL``.
