refactor(charts): remove useless conditional in onDataPointClickInternal (#8550)

To fix this, remove the duplicated `payload` operand in the `if` guard
inside `onDataPointClickInternal`.
The best minimal, behavior-preserving fix is:

- Keep the null/truthy guard for `payload`.
- Keep the function-type guard for `onDataPointClick`.
- Delete only the duplicated `payload &&`.

This change should be made in
`packages/charts/src/components/PieChart/index.tsx` at the
`onDataPointClickInternal` callback (around line 180 in the snippet). No
imports, new methods, or additional definitions are required.
