Add End-related loot to End cities

The current End city loot has only valuable equipment, metals, and gems, none of which fits the End theme. I think adding chests in non-treasure rooms that contain less valuable, but more End-themed loot would make the visit more immersive. The items that I think that should be added in these chests include, but are not limited to:

• Ender pearls/eyes of Ender
• Magenta dye/glass
• Purpur blocks/popped chorus fruits
• Chorus fruits/flowers
• Blaze rods/End rods

This can also grab more attention to End-themed building blocks as well.
