The standalone data_model cython binding was folded into the main cuopt wheel in NVIDIA/cuopt#1193. The replacement is from cuopt.linear_programming import DataModel.

Fixes notebook CI failure: ModuleNotFoundError: No module named 'data_model'

Tested locally in nvidia/cuopt:26.6.0a-cuda13.2-py3.14 container — both notebooks pass.
