There is no dedicated folder for the two shield textures in assets/minecraft/textures/entity

There is no dedicated folder for the two shield textures shield_base.png and shield_base_nopattern.png. This is unusual when compared to other entities that have multiple textures, where both are stored in their own sub folder for organization and clarity.

Steps to Reproduce:

1. Go to the following file path:
   C:\Users[user]\AppData\Roaming\.minecraft\versions[latest_version]
2. Right click the [version].jar] file, and open it in a file explorer (like 7zip or winrar)
3. Go to the following path inside the jar:
   assets\minecraft\textures\entity

Suggested Fix:

Add a sub-folder in textures\entity called shield, and put shield_base.png and shield_base_nopattern.png inside it.
