Fix the use of Pick type in type definition

This change was originally made in mifi#111. Pick type only takes two parameters: https://www.typescriptlang.org/docs/handbook/utility-types.html#picktype-keys

The keys should be unioned with `|`. `'path'` and `'animationData'` are separated with `,` which makes them invalid. They also don't need to be picked from `AnimationConfig` since we already add them in explicitly.
