There are unused texture files

Summary:
In the bedrock edition, there are some unused item and old block textures in the game files.
In the Java version, similar texture files were removed in 1.17 MC-108636.

Here are some of them (there are probably many more):

• resource_packs\vanilla\textures\items\quiver.png

• resource_packs\vanilla\textures\items\ruby.png

• resource_packs\vanilla\textures\items\boat.png

• resource_packs\vanilla\textures\gui (completely the entire folder, ui folder is used instead of this folder)

• resource_packs\vanilla\textures\ui\default_world.png

Steps to reproduce:

1. Find the textures listed above.

Observed results:
There are unused textures in the files.

Expected results:
There will be no unused textures.
