Labeled switch rule can have code block

Reports rules of switch expressions or enhanced switch statements with an expression body. These can be converted to code blocks.

Example:

  String message = switch (errorCode) {
    case 404 -> "Not found!";
    ...
  };

After the quick-fix is applied:

  String message = switch (errorCode) {
    case 404 -> {
                yield "Not found!";
            }
    ...
  };
