Missing GL version error on docker windows container while running pyvista

Hi,

I am trying to build a docker image based on windows container (mcr.microsoft.com/windows:20H2) to run on it a python project, and I am getting issues running pyvista in the built container. In fact I have used this repository script to set up OpenGL related features like headless displays in my windows container, but when trying to run tests involving Pyvista I am getting windows fatal exception error which I think it is related to this below :

Here the pyvista report about the windows container:

Update OSMesa on Windows

The current version of OSMesa on windows used here is mesa-10.2.4-1 which is 8+ years old and has all kinds of issues rendering which show up in PyVista's image regression tests, for example:

unnamed

This old version of Mesa is coming from @vispy's https://github.com/vispy/demo-data/raw/main/mesa/ (cc @larsoner)

I've started drafting a PR in #4 to add a DLL directly to this action to use but I don't know anything about PowerShell and windows so this is taking me a bit to debug.

Opening this issue to track the fact that we need to and are updating the OSMesa DLL for windows and to have a broader conversation to see if @vispy wants to update their OSMesa version
