[MC-197497] Smooth lighting transition from level 1 to 0 is not smooth

Blocks are lit up with jagged, non-smooth edges, even when smooth lighting is set to true. This only happens between light levels 0 and 1.

Doesn't just affect snow, it affects all blocks.

Best tested in a cave world.

~~Seems fixed (or at least improved) in 22w16b.~~ Edit: nevermind, this is still the case in 22w16b.

In 1.20.4

This seems to only occur when the block light level is transitioning from 1 -> 0 and the sky light level is 0. When sky light level is higher, the transition is smooth.
