The allowed heading levels for accordion are likely to be unique to accordion and also likely to change as support improves, so rather than set up a generic data type and composition, use a data type specific to that component and add it directly to the component settings.
Accordion support has only just been merged and never published, so this is a non-breaking change.
This PR also moves the accordion page to the top of the list in the example app backoffice, to match its position on the example app home page.
