Goat Horns not using custom cooldown groups

When specifying the use_cooldown component, a Goat Horn activates the cooldown group of other Goat Horns instead of a specified custom group, both on use and post-use.

Steps to Reproduce

1. Acquire a normal Goat Horn:

   /give @s minecraft:goat_horn

2. Acquire a special Goat Horn with a custom cooldown group:

   /give @s minecraft:goat_horn[minecraft:use_cooldown={seconds:1,cooldown_group:"custom"}]

3. Select the special Goat Horn and hold down right-click. This also triggers the other Goat Horn's cooldown.

4. Release right-click. The use_cooldown component triggers, but not in the custom cooldown group, as the other Goat Horn also goes on cooldown.

Expected Results

The special Goat Horn's cooldown should not trigger the regular Goat Horn's cooldown.
