The old version of prettier we were using didn't support the Flow syntax to access properties in a type using `SomeType['prop']`. This updates `prettier` and `rollup-plugin-prettier` to the latest versions. I added the prettier config `arrowParens: "avoid"` to reduce the diff size as the default has changed in Prettier 2.0. The largest amount of changes comes from function expressions now having a space. This doesn't have an option to preserve the old behavior, so we have to update this.
