🐞 Bug: `PieChart` donut mode does not support transparent inner circle

[engineer-dilnawaz]

Description

Description

When using the PieChart component with donut mode and setting
innerCircleColor="transparent", the center is not actually transparent.
Instead, it renders a filled circle (with default background), making it impossible to create a real donut chart with a see-through hole.

Steps to reproduce

Steps to Reproduce

<PieChart
  donut
  data={[
    { value: 45, color: 'white' },
    { value: 85, color: 'black' },
  ]}
  radius={70}
  innerRadius={35}
  innerCircleColor="transparent"
/>

Expected Behavior

The inner circle should be transparent, allowing the parent background (including gradients, images, or other components) to show through.

Actual Behavior

The inner circle is filled and blocks the background.
Setting transparent has no effect.
