[python] NumPy 2 experiment [WIP]

[johnkerl]

Issue and/or context: #2536

Changes:

Notes for Reviewer:

Main thing to watch for: NumPy 2.0 does not support Python 3.8, while we have not yet dropped support for Python 3.8 (#2141).

Per https://github.com/numpy/numpy/releases/tag/v2.0.0:

The Python versions supported by this release are 3.9-3.12.

I thought we'd need a bit in setup.py like

        # There is no Python 3.8 support for NumPy 2
        "numpy<2; python_version<'3.9'",
        "numpy; python_version>='3.9'",

but in hindsight it seems not -- a Python 3.8 asking to get NumPy will simply not be offered version 2 in the first place 😎

Oddly, the "Show package versions" bit in
https://github.com/single-cell-data/TileDB-SOMA/actions/runs/10585607673/job/29332572332?pr=2934
is showing even for Python 3.11

Run python scripts/show-versions.py
