✨ Allow for more easily using translatable components with MinecraftHelp

[jpenilla]

These changes allow for more easily using adventure's translation system with MinecraftHelp.

final MinecraftHelp<CommandSender> help = new MinecraftHelp<>(
  "/example help",
  audiences::sender,
  commandManager
);

help.messageProvider((sender, key, args) ->
  Component.translatable(
    "example.help." + key,
    Arrays.stream(args).map(Component::text).collect(Collectors.toList())
  )
);

help.descriptionDecorator(Component::translatable);
