Light Levels do not Render in Single-Block Spaces

[Wyatt-James]

Light levels do not render in one-block spaces, as pictured. I would like a toggle to enable this, as it is important for building some Redstone contraptions, specifically those that rely on grass growth.

I was sure there was already a config for it, but apparently the collision check option does not affect the block above check. I guess I need to add another option for it... or re-do the options somewhat. This will most likely only happen via the main development code though, so it won't arrive that soon in something like 1.19 or 1.20. Maybe a temporary release to just remove that check for a block above would be needed then.
