Is this the right issue type?

• Yes, I'm planning work for this project team.

Summary

After Automatic-Seeding-Feature #947 and Feat/946/default admin #964 merged in Carrot Mapper, users don't need to manually add superuser and seed data anymore, both locally and cloud-ly. So the docs site needs updating accordingly.

Acceptance Criteria

• Docs content related to manual add superuser and seed initial data updated according to the changes that have been made.

Tasks

• Places need updating
  - [ ] Quickstart for dev: https://carrot.ac.uk/mapper/dev_guide/quickstart#initial-data-preparation
  - [ ] Azure deployment: https://carrot.ac.uk/mapper/deployment/azure/steps#backend-app
