Describe the issue:

ob_shash is deprecated on Python 3.11:

numpy/core/src/multiarray/scalarapi.c:709:13: warning: ‘ob_shash’ is deprecated [-Wdeprecated-declarations]

This looks unnecessary 🤔, cached hash value for obj should not be computed yet:

numpy/numpy/core/src/multiarray/scalarapi.c

Line 709 in 28e624d

((PyBytesObject *)obj)->ob_shash = -1;

Reproduce the code example:

Run tests on Python 3.11.

Error message:

numpy/core/src/multiarray/scalarapi.c:709:13: warning: ‘ob_shash’ is deprecated [-Wdeprecated-declarations]
