FileTree component props type error.

[BHznJNs]

Currently the props type of FileTree is:

export type FileTreeProps = HTMLAttributes<HTMLDivElement> & {
  expanded?: Set<string>;
  defaultExpanded?: Set<string>;
  selectedPath?: string;
  onSelect?: (path: string) => void;
  onExpandedChange?: (expanded: Set<string>) => void;
};

Which inherited the HTMLAttributes<HTMLDivElement> so that the actual onSelect callback type will be (ReactEventHandler<HTMLDivElement> & ((path: string) => void)) | undefined
