Make Flashback's sky override option work with iris shaders.
Notice:
Compared to version 1.0.0, which covered the sky by rendering a box, version 2.0.0 directly disables the functions of
WorldRenderingPhase.SKY, WorldRenderingPhase.CUSTOM_SKY, WorldRenderingPhase.CLOUDS, WorldRenderingPhase.VOID, WorldRenderingPhase.SUN, WorldRenderingPhase.STARS, WorldRenderingPhase.MOON, and WorldRenderingPhase.SUNSET,
which should yield a better result. However, you must manually disable clouds in your shader settings. In version 1.0.0, the clouds only appeared to be covered, but in reality, they were simply beyond the boundaries of the green-screen box.

# Notice:
From versions 1.21 to 1.21.4, Minecraft’s sky rendering has changed, which also affects how Flashback and Iris handle sky rendering. As a result, this mod’s effect in 1.21 can not perform as expected, so please use it with discretion. If you have a solution, please share it!
