fix: ternary comment placement and indentation

[jtkiesel]

What changed with this PR:

Ternary expression comment placement and indentation are now aligned with those used by Prettier for JavaScript.

Example

Input

class Example {

    void example() {
        a
            ? // b
            b
            : // c
            c;
        a
            // b
            ? b
            // c
            : c;
        a ? // b
            b
            : // c
            c;
        a
            ? b // b
            : c; // c
    }
}

Output

class Example {

    void example() {
        a
            ? // b
              b
            : // c
              c;
        a
            ? // b
              b
            : // c
              c;
        a // b
            ? b
            : // c
              c;
        a
            ? b // b
            : c; // c
    }
}
