Fix misplaced argument comment in abstract methods (#12185 by @duailibe)

// Input
abstract class Foo {
  abstract bar(
    /** comment explaining userId param */
    userId
  )
}

// Prettier stable
abstract class Foo {
  abstract bar(userId);
  /** comment explaining userId param */
}

// Prettier main
abstract class Foo {
  abstract bar(
    /** comment explaining userId param */
    userId
  );
}
