Update README.md

[musm]

Basically all of these packages have been deprecated.

@SimonDanisch do you want to archive https://github.com/JuliaGL/GLWindow.jl https://github.com/JuliaGL/GLVisualize.jl ?
I was going through these repos trying to catch up to speed on latest Makie changes. Hopefully this better reflects the latest changes.

[SimonDanisch]

Yeah, sounds like a plan! @louisponet wanted to keep some of those alive, but I guess mostly GLAbstraction?

[musm]

The repo says GLAbstraction is archived by its owner https://github.com/JuliaGL/GLAbstraction.jl. Is that not true then?

[louisponet]

Yea Simon archived it, although in my opinion there's no real need to since it works with v1.6 and I think it's a valid abstraction layer over pure OpenGL. GLVisualize I don't think works or is used anywhere at all anymore. GLWindow, same thing, I think some of the nice abstractions that were in there were put in GLFW.jl itself now.

[musm]

@louisponet thank you for the reply. I went ahead and unarchived GLAbstraction and archived GLVisualize and GLWindow.

@louisponet it might be to your benefit to update the GLAbstraction readme to remove the deprecation notice.
