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!";
          }
  ...
};

The inspection only reports if the language level of the project or module is 14 or higher.
