numpy.bool is deprecated and is removed from numpy-1.24.x

[gschwind]

Hello,

Message shown when using numpy-1.23.3:

<stdin>:1: DeprecationWarning: `np.bool` is a deprecated alias for the builtin `bool`. To silence this warning, use `bool` by itself. Doing this will not modify any behavior and is safe. If you specifically wanted the numpy scalar type, use `np.bool_` here.
Deprecated in NumPy 1.20; for more details and guidance: https://numpy.org/devdocs/release/1.20.0-notes.html#deprecations
<class 'bool'>

With numpy-1.24.1 brightway2 does not import:

/lib/python3.9/site-packages/bw2data/data_store.py:172: FutureWarning: In the future `np.bool` will be defined as the corresponding NumPy scalar.  (This may have returned Python scalars in past versions.
