Update README about required Vulkan.

[nathan130200]

I've tried execute game from last sucessful build tree (yesterday) but this require vulkan... I suggest change in README to tell that it requires vulkan.

While older build (from release page) actually try open but crashes due an shader compilation error:

It doesn't require vulkan, you're running using the DX12 backend, the error message I put is misleading.
The issue is Limit 'max_storage_textures_per_shader_stage' value 4 is better than allowed 2 because you have a very old GPU. However I probably don't really require 4 storage textures, I'll try to take a look into that.

[Uriopass]

Should be fixed on latest master if it was just a matter of limits

[Uriopass]

But yeah, I don't expect much from very old gpus like this (10 y/o). I'm using modern rendering techniques and tools since I can't afford having separate rendering backends.

Thanks for the info!
