Defining SynchedEntityData via BoatMixin causes issues with other mods' boats

[unilock]

Description of the Bug Encountered
Wilder Wild defines a new type of SynchedEntityData for the vanilla Boat entity via mixin here:

WilderWild/src/main/java/net/frozenblock/wilderwild/mixin/entity/penguin/BoatMixin.java

Lines 43 to 44 in ba91723

	@Unique
	private static final EntityDataAccessor<Boolean> WILDER_WILD$BOOSTED = SynchedEntityData.defineId(Boat.class, EntityDataSerializers.BOOLEAN);

WilderWild/src/main/java/net/frozenblock/wilderwild/mixin/entity/penguin/BoatMixin.java

Lines 50 to 53 in ba91723

	@Inject(method = "defineSynchedData", at = @At("TAIL"))
	public void wilderWild$defineSynchedData(SynchedEntityData.Builder builder, CallbackInfo info) {
	builder.define(WILDER_WILD$BOOSTED, false);
	}

This causes issues with other mods that do the same thing, or even just extend the Boat class for their own boat types, due to reasons detailed in FabricMC/fabric-api#1049 and FabricMC/fabric-api#3482

Steps To Reproduce

1. Install Wilder Wild and Nature's Spirit v2.2.5 (the last version that extends vanilla's Boat class for its own boats)
2. Start the game, join a world, etc.
3. Place a boat from Nature's Spirit
4. The game crashes (if it doesn't, add some other mods; the crash is inconsistent)

Expected Behavior
No crash

Screenshots
N/A

Logs

Additional context
Same issue as #462 and #468, only with boat boosting instead of chest boat types this time

Perhaps Fabric's Data Attachment API could be used instead?

Bruhhhhhhhhhhhhh

I have found ZERO explanation about the attachment api and was made fun of in the fabric server when I asked after it was added :/

Oh my god they finally made proper docs????
