Replace np.alltrue() with np.all()

[iyanmv]

Summary

numpy.alltrue() was deprecated in NumPy 1.25.0 and removed in NumPy 2.0. Because of this, test_h2 fails on recent versions of NumPy.

This PR simply replaces np.alltrue() with np.all() as recommended by the NumPy 2.0 migration guide. Test will continue to work on older versions of NumPy.

It looks good to me, thanks!

@mrossinek @woodsp-ibm it looks like the pipelines are failing for three reasons:

1. The macos pipelines are failing because the Conda environment cannot be created correctly. On Windows and Ubuntu that step works.
2. For all pipelines, it looks like the package networkx is using np.float_, which is not supported in numpy>=2.0.0. From the pipeline logs it looks like we are using networkx==2.5.1, whereas the last version is the 3.4.2:

Collecting networkx<2.6,>=2.2 (from -r requirements-dev.txt (line 19))
  Downloading networkx-2.5.1-py3-none-any.whl.metadata (4.9 kB)

This error is likely to be fixed by changing the requirements-dev.txt.
3. Both pylint and mypy are failing due to errors unrelated to this PR. I can take care of that in another PR
