Refactoring:  
The main reasons for the following changes were matching the source code of SGJ

- Relocated enchantment PoO texture from `assets/moregates/textures/symbols/points_of_origin` to `assets/moregates/textures/symbols/enchantment/point_of_origin`
- Formatted JSONs and reordered keys to match SGJ default variants keys order
- Relocated symbol textures from `assets/moregates/textures/symbols` to `assets/moregates/textures/symbol`
- Removed duplicate textures to lower the mod size
- Removed unused textures
