Broken link in warning message regarding hinting the OS/driver to use discrete graphics adapter

[Alan-FGR]

Hello guys! I'm not creating an issue for this since it seemed overkill and there's probably some discussion involved.

The error message here has a broken link. Basically it was a gist that would show how to expose the symbols that hint the OS/driver to use the discrete GPU (for systems with both integrated and dedicated).

Basically the snippet was something like this:

extern "C"
{
    __declspec(dllexport) uint32_t NvOptimusEnablement = UINT32_C(1);
    __declspec(dllexport) uint32_t AmdPowerXpressRequestHighPerformance = UINT32_C(1);
}

Which need to be exported from the executable binary.

I'm not sure what other link could replace this one, but maybe it could be in 1st party docs so there's no risk of stuff breaking again?

OpenGL doesn't allow to select a discrete graphics adapter by default, so you need to export these variables in the executable or you can use this way

Next you need to set the values of these variables to 1, you can do it like this

The link is correct, it's just that an error appeared there during code refactoring. We need to remove XpressRequestHighPerformance from the link

The link (https://gist.github.com/statico/6809850727c708f08458XpressRequestHighPerformance) is indeed broken. @MikhailGorobets can you fix it?
