Labeled switch rule has redundant code block

Reports labeled rules of switch statements or switch expressions that have a redundant code block.

Example:

String s = switch (n) {
  case 1 -> { yield Integer.toString(n); }
  default -> "default";
};

After the quick-fix is applied:

String s = switch (n) {
  case 1 -> Integer.toString(n);
  default -> "default";
};

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