Glow squids spawn even if the block light is above 0

The "complete darkness" rule for spawning glow squids seem to have been unintentionally removed when the spawning rules for glow squids were changed in snapshot 21w40a.

 

How to reproduce:

1. Create a creative default world in one of the affected versions.
2. Locate an aquifer below height 30 using spectator mode.
3. Fully light the aquifer with lanterns (or other waterloggable light sources), and make sure that none of the water blocks are completely dark).
4. Move away and wait for glow squids to spawn in the area.
