Component | Sankey: Add node collapse feature

[lee00678]

Adding a feature to Sankey to allow pre-collapsed node.
Three new props:

   /** Enable node collapse functionality. When enabled, clicking on nodes will toggle their collapse state. Default: `false` */
  enableNodeCollapse?: boolean;
  /** Node collapse animation duration, ms. Default: `300` */
  collapseAnimationDuration?: number;
  /** Field name in the node data that indicates if a node should be pre-collapsed.
   *  For example, if set to "disabled", nodes with `disabled: true` will start collapsed.
   *  Default: `undefined` */
  disabledField?: string;
