Support Numpy 2.0

[ccoulombe]

Roadmap to support and deploy Numpy 2.0

• [x] Build Numpy 2.1.1 wheels
• [x] Test builds with numpy (with 1.x ABI compat, and not)
• [x] #156
• [x] #154
• [x] Deploy patched 2023 wheels
• [x] Build pandas, scipy and matplotlib compatible wheels
• [x] Deploy numpy, pandas, etc. wheels for 2023
• [x] #161
• [x] #160
• [x] #157
• [x] #158
• [x] #159
• [x] Add troubleshooting issue to Trouble Shooting section on Python page

By adding numpy 2.0, we risk of :

1. breaking modules whichs used oldest-supported-numpy and uses a scipy-stack for its numpy
2. breaking of users environment where they install any version of numpy and use scipy-stack (or any module that uses it, eg arrow or opencv).
3. breaking current wheels that were built with 1.x and not constrained to numpy<2.0
4. breaking current jobs of users that do not specify versions or use a requirements file

Numpy 2.1.1 + matplotlib 3.9.1 (built with oldest-supported-numpy), no 1.x compat

>>> import matplotlib

A module that was compiled using NumPy 1.x cannot be run in
NumPy 2.1.1 as it may crash. To support both 1.x and 2.x
versions of NumPy, modules must be compiled with NumPy 2.0.
Some module may need to rebuild instead e.g. with 'pybind11>=2.12'.

If you are a user of the module, the easiest solution will be to
downgrade to 'numpy<2' or try to upgrade the affected module.
We expect that some modules will need time to support NumPy 2.

Cool, au moins numpy donne une erreur compréhensible à l'usager.

numpy 2.1.1 and the wheelhouse are now synced to the systems.
