test(openapi): refresh spec fixture to v37.0 and update assertions

The bundled OpenAPI spec fixture (tests/data/specs.yml) was a v22.0
snapshot from 2021. Replace it with the current live spec (v37.0) from
https://apispec.connect.cloudblue.com/connect-openapi30.yml so the
introspection tests validate against the API's real, current structure.

Update the exact-match assertions in test_openapi.py whose expected
values changed with the new spec: get_namespaces (11 -> 21),
get_collections (18 -> 29), get_actions and get_nested_collections for
products. No client code changes: the client is spec-agnostic and only
loads the spec for optional help/validation.
