Label isn't affected by format prop

[bakoushin]

Label isn't affected by format prop – function passed to format prop is actually used for formatting tooltip value only, despite docs says it should be used also for label as well.

I expect that the same function from format prop should be used for formatting both tooltip and label as well, according to the docs.

Simply pass format function to labels set values.

labels={{
            0: formatSlider(minSlider),
            100: formatSlider(maxSlider),
          }}
