[The documentation](https://ant.design/components/select/) lists the `tokenSeparators` property on the `Select` component, but the TypeScript definition for the component does not contain the `tokenSeparators` property. The underlying `rc-select` component [defines tokenSeparators](https://github.com/react-component/select/blob/master/src/Select.jsx#L79) as `PropTypes.arrayOf(PropTypes.string)`, so I've added it as an optional TypeScript property of type `string[]`.
