nnunetv2 support for numpy >=2.0

[2025-05-01T13:49:18.474Z] 

[2025-05-01T13:49:18.474Z] A module that was compiled using NumPy 1.x cannot be run in

[2025-05-01T13:49:18.474Z] NumPy 2.2.5 as it may crash. To support both 1.x and 2.x

[2025-05-01T13:49:18.474Z] versions of NumPy, modules must be compiled with NumPy 2.0.

[2025-05-01T13:49:18.474Z] Some module may need to rebuild instead e.g. with 'pybind11>=2.12'.

[2025-05-01T13:49:18.474Z] 

[2025-05-01T13:49:18.474Z] If you are a user of the module, the easiest solution will be to

[2025-05-01T13:49:18.474Z] downgrade to 'numpy<2' or try to upgrade the affected module.

[2025-05-01T13:49:18.474Z] We expect that some modules will need time to support NumPy 2.

Start by running tests/integration/test_integration_nnunetv2_runner.py and inspect the import path shown in the traceback. Trace the NumPy compatibility failure through the nnUNetV2 integration setup; done means this integration test runs successfully with NumPy 2.x without the reported initialization warning.
