Wrong documentation for haptic feedback

[Aquets]

Issue description

The documentation in the README.md file for LineChart haptic feedback is incorrect.

It is suggested to use invokehaptic on onActivated and onActivated of <LineChart.CursorCrosshair /> but it isn't working. I solved it using it on onCurrentIndexChange of <LineChart.Provider />

Suggested code example

I suggest to change the code example in the documentation like this:

import * as haptics from 'expo-haptics';

const data = [...];

function invokeHaptic() {
  haptics.impactAsync(haptics.ImpactFeedbackStyle.Light);
}

function Example() {
  return (
    <LineChart.Provider data={data} onCurrentIndexChange={invokeHaptic}>
      <LineChart>
        <LineChart.Path />
        <LineChart.CursorCrosshair>
          <LineChart.Tooltip />
        </LineChart.CursorCrosshair>
      </LineChart>
    </LineChart.Provider>
  )
}
