Wheels built with numpy2

[t20100]

Describe the bug

Wheels currently available in pypi (2024.2.6) are not compatible with numpy v2. It would be great to have wheels with numpy 2 support since it has been released.

To Reproduce Steps to reproduce the behavior:

1. Install numpy v2 and pyopencl 2024.2.6 from a wheel
2. Run import pyopencl
3. See exception: ImportError: ImportError: numpy.core.multiarray failed to import

>>> import pyopencl

A module that was compiled using NumPy 1.x cannot be run in
NumPy 2.0.0 as it may crash. To support both 1.x and 2.x
versions of NumPy, modules must be compiled with NumPy 2.0.
Some module may need to rebuild instead e.g. with 'pybind11>=2.12'.

If you are a user of the module, the easiest solution will be to
downgrade to 'numpy<2' or try to upgrade the affected module.
We expect that some modules will need time to support NumPy 2.

Same problem. Is there any temporary workaround before stable release?

[t20100]

Installing "numpy<2" is an easy fix.

https://github.com/inducer/pyopencl/releases/tag/v2024.2.7 should address this. It should be on the package index soon.
