feat: basic mock

[nohehf]

Description

Fixes #33

Generates a basic response example for each query. Not perfect for now but useful however as it generates a base that can be manually extended by the users. Improvements will be made.

Stuck: example responses are ok in the collection, however, when generating a mock server with postman it doesn't pick up the correct example for the request. I believe that could be an issue on Postman side, will investigate in #33 before merging.

Closing the PR as the is stuck as long as postman won't fix the imports: see #33.
