Scenario bundles: order of tabs in editing backend counterintuitive

Description of the issue

I started writing a course on how to add information to the scenario bundles. I stumbled across the following: the scenarios themselves are only the second last heading in the backend. I assume users would work their way from the left to the right. So I would suggest to move the scenario button right after basic information. I think this makes the navigation of adding information easier to the users as they then already described their scenarios before they enter further context information.
