`Role` attribute for individual bars

[JinCoreana]

Is your feature request related to a problem? Please describe. I am using ResponvieBar component and found that role attribute does not get inherited to the <rect> of the individual bars whilst I can pass aria-label to them using barAriaLabel attribute. I believe role and aria-label should be paired up in this case.

Describe the solution you'd like Please inherit role to the children <rect> or enable another prop like barRole to manually assign role to each bar.

Describe alternatives you've considered I have implemented a workaround that override bars by passing the below CustomBars component to layers attribute instead of the default bars But I wish this can be done automatically.

 const CustomBars = (props: { bars: ComputedBarDatum<BarDatum>[] }) => (
    <>
      {props.bars.map((bar) => {
        return (
          <rect
            {...bar}
            key={bar.key}
            role="figure"
            fill={bar.color}
            aria-label={bar.label}
            tabIndex={0}
          />
        );
      })}
    </>
  );

Additional context Here is the assesibility assessment taken in the official nivo doc and I could check the same issue occurs.
