Mana Seed Shaders (Character Edition) Updated

I've done a minor update for Mana Seed Shaders for Unity. As I will soon be releasing the Farmer Base equivalent as a separate product, I have renamed this project to Mana Seed Shaders for Unity (Character Edition). I've also updated to the current version of ShaderGraph and built these shaders in Unity version 2021.3 to stay inline with Unity's LTS model. I have thoroughly tested these shaders work perfectly on 2021.3, 2022.3, and Unity 6.
