Update WailaCommonRegistrationEventJS.java

Allow registering BlockDataProviders from classes that don't extend BlockEntity, as is the case within Jade itself (thus allowing data providers for blocks that don't have blockentities).

I'm not sure where you saw that Jade itself doesn't need a class that extends Blockentity. This is the version I was basing this API off of, and the interface directly requires it to be a BlockEntity Class and not just any class.

        /**
     * Register an {@link IServerDataProvider<BlockAccessor>} instance for data syncing purposes.
     *
     * @param dataProvider The data provider instance
     * @param block        The highest level class to apply to
     */
    void registerBlockDataProvider(IServerDataProvider<BlockAccessor> dataProvider, Class<? extends BlockEntity> block);

Ah, my bad, I failed to notice that accepting any class was from a very recent PR to Jade and not in the release version yet.
