Documentation - incorrect API documentation
## Description
- `GET /api/v1/assignment/{aid}/submission/{sid}` endpoint is incorrect. The `SubmissionController` does not return a status field for example.
- token fields are incorrect: 'TokenAuthenticationFilter' checks for `Auth-Token` in the header or `auth-token` as a parameter
## Priority - Low
Should eventually be updated
## Definition of done
When the API documentation reflects the `SubmissionController` logic
