Release 2.4.0

• Changed the type of comments from Strings to Components. The value of Config#comment is now the name of a method that provides the comment. For example:

  - @Config(comment = "This is a comment!")
  - public static Object exampleComment = null;
  + @Config(comment = "exampleCommentMethod")
  + public static Object exampleComment = null;
  + private static Component exampleCommentMethod() {
  +     return Component.literal("This is a comment!");
  + }

• Added two API methods: ModConfig#getDefault and ModConfig#getComment.
• Updated to Minecraft 1.21.6.
