Release 2373
Trello card
Context
As part of a design refresh, we have decided to revisit the profile updating page (before we do anything more radical). The current page is rather long, so we're splitting it according to the <h2/3> tags. This design takes elements of the Publish service, so there's some evidence to suggest this will work.
Changes proposed in this pull request
- Split school profile into tabs
- Update heading to match new design
