Nodes with trailing newlines retain the trailing newlines after sort

[nedjulius]

Complicated the allowLineSeparatedGroups option

For example:

const styles = stylex.create({
  foo: {
    display: 'flex',
    borderColor: 'red',

    alignItems: 'center',
  }
});

After replacing properties display and borderColor in the ObjectExpression.properties list, we get:

const styles = stylex.create({
  foo: {
    borderColor: 'red',

    display: 'flex',
    alignItems: 'center',
  }
});

The expected behavior:

const styles = stylex.create({
  foo: {
    borderColor: 'red',
    display: 'flex',

    alignItems: 'center',
  }
});
