Change 3 prop normal textures from size 518x518 to 512x512

[TrafficConeOfSchooling]

Description of the proposed changes

I have resized 3 of the normal textures for the ancient earth props to 512 x 512:
eg_bush01_normalsTS.dds
eg_bush02_normalsTS.dds
eg_bush03_normalsTS.dds
These textures were originally at size 518 x 518 which is incompatible with BC3 texture compression.

Hence this error message when the map editor loads the ancient-earth props section.

Testing done on the proposed changes

I took the entire ancient-earth prop folder out of the game files and pasted it into a test map's props folder.
Loading the map folder's props still resulted in the error.
Replacing the 518 x 518 textures with 512 x 512 versions allowed every prop in the map folder to be loaded and used properly.

A rabbit hops through textures fine,
512 by 512, now they align!
Props resized, BC3 blessed,
Ancient earth editors pass the test! 🐰✨

This is a great find 👍 , the game is also unable to process non-power-of-two textures in some area's of the game, such as terrain stratum textures. It rescales the texture internally to the next power-of-two as it tries to load the texture.
