Wrong type definitions for aria-valuetext formatters

[tomasfabry]

For the slider there is the following type definition in the SliderProps interface:

ariaValueTextFormatterForHandle?: string;

According to the documentation, there should be something like this:

ariaValueTextFormatterForHandle?: (value: number) => string;

---

Similarly, for the range slider, there is the following type definition in the RangeProps interface:

ariaValueTextFormatterGroupForHandles?: string | Array<string>;

But there should be:

ariaValueTextFormatterGroupForHandles?: Array<(value: number) => string>
