## Scope
Admin routes
## What
Add OAS `required` to response schemas.
## Why
Code generator can use the `required` property of a schema to mark fields as optional or not when generating TS types.
## Test
* Run `yarn build`
* Run `yarn openapi:generate`
* Run `yarn redocly preview-docs docs/api/admin/openapi.yaml --config=docs-util/redocly/config.yaml`
* Open the documentation preview URL in a browser (http://127.0.0.1:8080)
* Expect responses to have their fields declared as `required`
