Documentation of 'activekey' prop inconsistent

[jorisw]

The documentation for this project says the component accepts prop activeKey here and activekey in the example. Should be activekey, according to the code in the component.

Should be activekey, according to the code in the component.

But I can't find any code like activekey. Such as https://github.com/react-component/collapse/blob/master/src/Collapse.jsx#L17 .

The docs however mention activekey instead of activeKey.
