`smithy format` puts postfix inline comments in the wrong place

[rhernandez35]

smithy format will turn this:

operation Demo {
    input: Unit // No input
    output := {
        foo: String
    }
}

into this:

operation Demo {
    input: Unit

    // No input
    output := {
        foo: String
    }
}

I would expect a trailing comment to adorn the syntactical element it's sharing a line with and not with the element following it.
