MAINT: NumPy normalize_axis_tuple

* this function moved from NumPy core to the public
API in recent NumPy builds, and is causing
SciPy CI failures here:
https://github.com/scipy/scipy/actions/runs/6555137521/job/17803175138?pr=19402

* normally I'd use PEP440 for this (either
vendored or through the appropriate PyPA lib)
but maybe you'd prefer to cheat like this
on major version vs. more infrastructure?
