Documentation not in line with Swagger

[markams]

For development we assume the Swagger is the truth.

We see differences between the documentation on GitHub and Swagger.

For example, the Activity Data

Swagger
https://eu-str.sdep-pilot.eu/swagger/index.html#/str/post_str_activity_data

GitHub
https://github.com/SEMICeu/STR-AP/blob/main/prototype/5.%20Documentation%20for%20stakeholders/Platforms.md#412-endpoints-for-platforms

In Github data about the areas is missing:

      "competentAuthorityId_area": "competentAuthorityId_area",
      "competentAuthorityName_area": "competentAuthorityName_area",
