Remove NumPy <2 pin

[seberg]

This PR removes the NumPy<2 pin which is expected to work for
RAPIDS projects once CuPy 13.3.0 is released (CuPy 13.2.0 had
some issues preventing the use with NumPy 2).

[jakirkham]

Now that CuPy 13.3.0 is out, restarting CI and marking this ready for review

Changes looked good to me.

I double-checked that this project doesn't have a build dependency on numpy, so no need to add any pins for build time.

Looked around at all the other uses of numpy and I think this got all of them. Assuming CI passes, I think this is good to go.

AFAICT numpy is not used in raft-dask

$ git grep numpy -- python/raft-dask/ | wc -l
       0

Also the Conda package doesn't include it

raft/conda/recipes/raft-dask/meta.yaml

Lines 61 to 76 in f1cc0fb

	run:
	{% if cuda_major == "11" %}
	- cudatoolkit
	{% else %}
	- cuda-cudart
	{% endif %}
	- {{ pin_compatible('cuda-version', max_pin='x', min_pin='x') }}
	- dask-cuda ={{ minor_version }}
	- rapids-dask-dependency ={{ minor_version }}
	- joblib >=0.11
	- nccl >=2.9.9
	- pylibraft {{ version }}
	- python x.x
	- rmm ={{ minor_version }}
	- ucx-py {{ ucx_py_version }}
	- distributed-ucxx {{ ucxx_version }}

The origin of this numpy line in raft-dask's wheels traces back to the addition of wheels in PR ( #1013 ). Though not seeing any discussion about why numpy was added there. Even at the time conda raft-dask packages did not depend on numpy. Am guessing this was just copied into the different RAFT wheel packages. So it is likely just an oversight that this hasn't already been cleaned up

---

Though pylibraft, used by raft-dask, does use numpy

$ git grep numpy -- python/pylibraft/ | wc -l
      52

Also pylibraft already includes numpy as a dependency

raft/conda/recipes/pylibraft/meta.yaml

Line 68 in a773fa5

- numpy >=1.23,<3.0a0

raft/python/pylibraft/pyproject.toml

Line 35 in a773fa5

"numpy>=1.23,<3.0a0",

So we can be confident numpy will be in the environment raft-dask is installed into even though it appears raft-dask itself doesn't need it

---

Given all of this, took this opportunity to clean this up and align our packages on the handling of this dependency

There was a network error in this CI job. Will wait for running CI jobs to complete and then restart failed jobs

Edit: Looks like that fixed it
