Replace numpy.alltrue with numpy.all

[robotAstray]

Summary

This pull request addresses issue #75 related to the deprecation of alltrue in favor of all in numpy versions 1.25 and later. The tests in Qiskit Cold Atoms were failing when run with versions >= 1.25.

Changes:

Replaced usages of numpy.alltrue with numpy.all throughout the codebase, to be specific in:

• test/test_fermion_circuit_solver.py
• test/test_spin_circuit_solver.py

Cool. This looks mostly good to me. Two minor comments:

• Could you also update the requirements such that numpy is not pinned anymore ? Normally, this should be enabled by this PR.
• Could you add a reno file that describes the changes of this PR ?

@fretchen, I have added the release notes and removed the specific version requirement for Numpy by substituting numpy >= 1.17 with just numpy. (I removed the lower bound requirement so that the project works with any version of Numpy, including versions released after the current requirements was set.)
