Add some tests for parameters

[magicDGS]

Currently the tests implemented are only against required ones, but we should provide some more newman/postman tests to check if we are in sync with the API.

Example of a test for the misc=yes parameter is provided on the branch: https://github.com/magicDGS-gaming/ygoprodeck-openapi/tree/magicDGS/test_misc_param

Nevertheless, this is blocked by an issue with portman (see apideck-libraries/portman#484)
