[MC-223301] Goats not taking damage when attacking with Thorns armor equipped

When a goat rams a player wearing armor enchanted with Thorns, it will not take damage, even though it is attacking Thorns armor.

Steps to reproduce:

Equip a piece of armor that has the Thorns enchantment
Summon a goat
Do /execute as @e[type=minecraft:goat,limit=1,sort=nearest] run data modify entity @s Brain.memories."minecraft:ram_cooldown_ticks".value set value 1
Wait for the goat to ram you, if it doesn't, repeat the command
The goat will not take damage when it hits you

Evidence:

Most likely cause: Goat rams might be handled with a different system from regular attacks

Proposed solution: Modify the Thorns enchantment to apply to goat rams as well
