Description

This is a quick update to pyproject.toml and the CI test suite to ratchet the supported versions of python to include 3.11 - 3.13

Fixes #3164.

This is currently limited by vtk not supporting Python 3.13. Here is the issue tracking this: https://gitlab.kitware.com/vtk/vtk/-/issues/19489

It looks like VTK now ships 3.13. @pshriwise or @paulromano, could you trigger GHA to rerun?

[paulromano]

Still failing as there are no Python 3.13 wheels on PyPI

[MicahGale]

My bad. I misinterpreted what had happened in the VTK repo.

Update. VTK is being held back by mpi4py. mipy4py 4.x does support 3.13, but they are pinned to version 3.x, which has no plans to support 3.13. So until they are able to migrate to the next release of mpi4py, which will be non-trivial, this upgrade is blocked.

The changes have been made, but are not currently planned to be incorporated into the next release yet.
