MAINT: update min version of python to 3.11.

Two  reasons

1. Numpy 2.3 requires python 3.11 or above
2. NumPy 2.3 is required to fix some annoying FPU warnings, see
   numpy/numpy#28687 (comment)

We can always relax those versions later as we don't actually rely on
specific recent versions of NumPy/SciPy
