Remove xwayland warning

[Starbuck5]

2.5.0.dev2 adds wayland support to our wheels, but the warning PyGame seems to be running through X11 on top of wayland, instead of wayland directly still persists.

To choose wayland, users need to set the environment variable SDL_VIDEODRIVER=wayland

Blubberquark, who committed the warning, said the purpose was to show people whether they were running in Xwayland for bug reporting purposes.

I propose

• We add this info to pygame.print_debug_info
• Remove the warning
• Possibly add an example of setting wayland to our documentation of SDL_VIDEODRIVER
