Updates to allow Python >3.10 support

[ZacharyPuls]

• Update scikit-learn to latest (1.7)
• Edit deprecated numpy functions for 2.x support (np.product() -> np.prod(), np.mat() -> np.asmatrix())
• Change np.where(G.graph[i, 0] != Endpoint.NULL.value)[0] (maybe was a typo?) to np.where(G.graph[i, :] != Endpoint.NULL.value)[0] in pyrca/thirdparty/causallearn/search/ScoreBased/GES.py

Unit tests are passing:
