Profile.games.quickplay.played should be of type number

Hi, I think
`Profile.games.quickplay.played` should be a number. in `index.d.ts` it is declared as `undefined` :)

I didn't want to make a Pull Request since it seemed a bit petty to me, and I wasn't quite sure about your reasoning behind declaring it as `undefined`
