encoding/openapi: add test cases for non-empty lists

An upcoming change to the CUE API to make lists consistent with structs for concreteness exposed a reliance of encoding/openapi on the current inconsistency. It also showed that despite there being logic in encoding/openapi for dealing with non-empty lists, that logic isn't tested anyway. Add a couple of test cases so that the behavior change in the upcoming CL will be clear. Note that the results here are not actually valid in OpenAPI 3.0, which does not support the form of `items` generated here (see #3480).
