Subject: [PATCH] Replace apivore with rswag for api tests (#969)

* Replace apivore api tests with rswag
* move to OpenAPI Spec 3.0.1
* a swagger UI is now reachable at http://localhost:3000/api-docs/index.html
*  swagger file is generated by running  `RAILS_ENV=test rails rswag`
    and it was moved from /docs/swagger.v1.yml to /swagger/v1/swagger.yml

-    [Foodsoft](https://github.com/foodcoops/foodsoft) is web-based software to manage

-
-
-    This is a description of Foodsoft's API v1.
-
-
-    Note that each food cooperative typically has their own instance (on a shared
-    server or their own installation), and there are just as many APIs (if the Foodsoft
-    version is recent enough).
-    This API description points to the default development url with the default
-    Foodsoft scope - that would be [http://localhost:3000/f](http://localhost:3000/f).
-
-    You may find the search parameters for index endpoints lacking. They are not
-    documented here, because there are too many combinations. For now, you'll need
-    to resort to [Ransack](https://github.com/activerecord-hackery/ransack) and
-    looking at Foodsoft's `ransackable_*` model class methods.
