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).

EDIT: Sorry, converted back to draft again, NumPy 2 is not yet picked up.

Note that cuxfilter depends on cuspatial

cuxfilter/dependencies.yaml

Line 200 in ca63e9d

- &cuspatial_unsuffixed cuspatial==24.10.*,>=0.0.0a0

So this depends on PR: rapidsai/cuspatial#1441

Yeah, sorry, I unmarked draft too early, but I think once things are in place and NumPy is picked up we can make it no-draft again and it should be good.

[jakirkham]

All good. Was more looping in James as we had discussed the cuSpatial NumPy 2 PR earlier

I've taken over rapidsai/cuspatial#1441 and so am testing here too.

Got cuspatial to a state where it can be installed alongside Numpy (2.0.2): rapidsai/cuspatial#1441 (comment)

I pushed commits here to use the packages built from that PR's CI. Let's see if it'll be enough to loosen the pin here!
