Add a collabsible details component #1802
Description
Visual
Context
A pattern has emerged at SumUp to display FAQs and similar content in collapsible sections. Essentially, this is a styled version of the <details> HTML element.
State
The component has an open and closed state. Circuit UI already exports the useCollapsible hook that abstracts this state logic.
Progressive enhancement
The component should fill the full width of its parent on all viewports. It should work without JavaScript using the default behaviour of the <details> HTML element.
