fix(adaptive-sidebar): ensure rendered sidebar can have accessible name

adds the aria-label and aria-labedlledby props to the component which are applied when the component
is rendered as a modal. This ensures consumers have the means to give the component an accessible
name when needed

 To use the adaptive sidebar, import `AdaptiveSidebar` into your project. All content within the `AdaptiveSidebar` component is determined by the user; by
 default, the component will be empty, allowing for complete control of layout, etc.
 
+As the `AdaptiveSidebar` can be rendered as a modal, it is **strongly** recommended that the component is given an accessible name.
+This can be generated via the `aria-label` or `aria-labelledby` attributes.
