Why this change?
This is a first pass at styling the editor for creating/editing/updating
an objects typed theme setting. Only the desktop view is being
considered at the current moment.
The objects typed theme setting is still behind a feature flag at this moment so there is no need for us to get the styling perfect. The purpose of this PR is to get us to a state which we can quickly iterate with a designer on.
