Summary: 

The item_damage field was renamed to damage

Impact:

In the Superhero Jailbreak map of ours, there is a reference to item_damage rather than damage, which results in the warning being printed to the content log

Repro Steps:

1. Open the Superhero Jailbreak map by Spark Squared from the Marketplace
2. Notice the content log error

Observed Results:

There is an error which states:

[Components][warning]-Superhero Jailbreak | actor_definitions | C:/Users/dest/AppData/Local/Packages/Microsoft.MinecraftUWP_8wekyb3d8bbwe/LocalState/games/com.mojang/minecraftWorlds/SuperheroPrison/behavior_packs/superhe_bp | minecraft:pig | minecraft:entity | component_groups | minecraft:pig_saddled | minecraft:boostable | boost_items | [0] | item_damage | Incorrect field name "item_damage" in boost_items, please use name "damage".

Expected Results:

There is no content log warning
