Fragment function showing texture without explicitly using it

[Skyvastern]

Your Godot version:
Godot v4.0.3.stable

Issue description:
Under the Using TEXTURE built-in subheading, for the following example code -

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

It says that it will show a white rectangle, without setting a texture. But in Godot, the texture still shows up, and color is added over it. So basically, the above code does the same thing as this -

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

So I think either something is wrong in the docs, or something is wrong in Godot.

I think this may be a duplicate of #7458

This was fixed by #8583.
