the new Numpy v2.0.0 break the package

numpy v2.0.0 was released yesterday, and it broke the pythoncall unfortunately. if calling `using PythonCall` with a brand new environment, numpy v2.0.0 would be automatically installed and then the error would pop up.

Start by reproducing the failure in a brand-new environment with `using PythonCall` and NumPy v2.0.0 installed automatically. Capture the reported error, then inspect how PythonCall resolves or uses NumPy. Done means a fresh environment no longer fails with the released NumPy version, with a regression check for this setup.
