Update to pygame 2.0.0

[hasii2011]

The production release; pygame says OpenGL supported in feature flags but I cannot import it

I need to put it in the package requirements now

[hasii2011]

Does not run in StarTrekPy, because of OpenGL; Used to be I did not have to import OpenGL; The Albow test program works here;

Broken on Big Sur
