fix: break nested ternaries together

[jtkiesel]

What changed with this PR:

Nested ternaries are now broken together as a single group, rather than individually, as Prettier TypeScript does.

Example

Input

class Example {

  void example() {
    aaaaaaaaaa ? bbbbbbbbbb : cccccccccc ? dddddddddd : eeeeeeeeee ? ffffffffff : gggggggggg;
  }
}

Output

class Example {

  void example() {
    aaaaaaaaaa
      ? bbbbbbbbbb
      : cccccccccc
        ? dddddddddd
        : eeeeeeeeee
          ? ffffffffff
          : gggggggggg;
  }
}
