Outdated information in "Your first 2D shader"?

[thiagola92]

Your Godot version: v4.0.3.rc2.official [2ac4e3bb3]

Issue description:
In the section "Using TEXTURE built-in" mentions that i need to read the texture, otherwise i will have an all white rectangle.
After testing I noticed that didn't made difference, is this right?

void fragment(){
  //this shader will result in an all white rectangle
  COLOR.b = 1.0;
}

void fragment(){
  COLOR = texture(TEXTURE, UV); //read from texture
  COLOR.b = 1.0; //set blue channel to 1.0
}

URL to the documentation page: https://docs.godotengine.org/en/stable/tutorials/shaders/your_first_shader/your_first_2d_shader.html#using-texture-built-in

I confirm that page needs updating- the new behaviour seems more reasonable to me, but the docs need to reflect this correctly:

This is true on Nvidia (as tested), but I am not 100% this is the case on other cards/render hw, such as integrated graphics or software acceleration. I've seen those behave differently on uninitiated data on CPU- can someone check if it works the same for Intel/AMD integrated graphics/Mesa?

@thiagola92 @Skyvastern which hw stack are you using?

CPU: Intel i5-7600K (4) @ 4.200GHz
