Accordion content props gets spread to multiple elements

```tsx
return (
setIsOpen(!open)}>
{label}
Here is some content

);
```

Then the rendered HTML has two elements with the same id, which is [invalid HTML](https://html.spec.whatwg.org/multipage/dom.html#the-id-attribute):

```html

Similarly, if I set any other attributes, such as `className` on the `AccordionContent` component, those attributes will be set on both the `ExpandCollapse__panel` and `Accordion__panel` elements.
