4.0.7 (1.21.5)

Fixed a bug that let the top layer of water render inside of Mesoglea again.
- A mixin that is now redundant has been removed in the process.
Slightly optimized shadow rendering.
Fixed Nematocyst rendering.
- Nematocyst rendering has finally been fixed with Sodium on all versions!
- Nematocyst rendering has been fixed with the Vanilla renderer on all versions!
  - Do note that this had already worked fine on Vanilla 1.21.1 and below, so players using these versions without Sodium will not notice a difference.
