Detailed description

Describe in detail the issue you're having.

The StructuredListWrapper has a border prop which does nothing. This may have been a selector used in v9 that was removed in v10.

You can see in the React component that this prop is supposed to apply a css selector:

    const classes = classNames(`${prefix}--structured-list`, className, {
      [`${prefix}--structured-list--border`]: border,
      [`${prefix}--structured-list--selection`]: selection,
    });

But, if you look at the styles for it, the selector doesn't exist.

It seems like this prop should be deprecated.
