Wrongly declared array not caught as error

[benjamin-mogensen]

Describe the bug The OAS file below has a wrongly declared array in the response. It states type: array and last line, and is missing an items key. Spectral does not catch this as an error. However, deploying such OAS in Apigee will not work as Apigeee uses Swagger parser which catches this error.

                    items:
                      type: array

To Reproduce

1. Use above OAS, create file oas-array-wrong.yaml
2. Run CLI spectral lint oas-array-wrong.yaml
3. Output is No results with a severity of 'error' found!

Expected behavior The wrongly declared array should be treated as an error as you cannot have an array declared without stating what type the items are.
