The scipy.linalg function triu was removed in SciPy 1.13

To import from karateclub import GraphReader it is necessary to import from scipy.linalg import triu (see the Traceback bellow):

But since the scipy.linalg function triu was removed in SciPy 1.13, to make it work, we need "scipy<1.13". Therefore the modification on the setup.py file.
