[MC-307799] Vulkan does not load shaders when there are comments at the beginning of the file

Steps to reproduce the bug:

Try loading the shaders with OpenGL
Try loading the shaders with Vulkan

This error occurs with Vulkan:

[Render thread/ERROR]: Couldn't compile FRAGMENT shader minecraft:core/gui: Couldn't parse GLSL: 0:1: error: '#version' : must occur first in shader

even though the comment should just be ignored
