The depth strider and respiration enchantments no longer function on horse armor

The Bug:

The depth strider and respiration enchantments no longer function on horse armor.

This issue was first introduced in 24w05a. It's important to note that thorns, curse of vanishing, and feather falling enchantments continue to operate as expected.

Steps to Reproduce:

1. Summon a large area of water along with a horse wearing diamond horse armor enchanted with depth strider 3 by using the commands provided below.

   /fill ~1 ~-1 ~1 ~15 ~-1 ~15 minecraft:water

   /summon minecraft:horse ~ ~ ~ {Tame:1b,body_armor_item:{components:{"minecraft:enchantments":{levels:{"minecraft:depth_strider":3}}},count:1,id:"minecraft:diamond_horse_armor"},SaddleItem:{count:1,id:"minecraft:saddle"}}

2. Mount the horse, ride it into the water, and observe if the depth strider enchantment increases the horse's movement speed while in water.

Observed Behavior:

The depth strider and respiration enchantments no longer function on horse armor.

Expected Behavior:

The depth strider and respiration enchantments would function on horse armor just like how they did in prior versions of the game.
