Issue:
Issues detecting on Ingress
Trying to detect on an ingress object:

```bash
cat << EOF | pluto detect - -v=10
apiVersion: networking.k8s.io/v1beta1
kind: Ingress
EOF
```

And I see the following error and response:

```
I0501 10:38:38.954095 1267123 versions.go:98] invalid json: invalid character 'a' looking for beginning of value
There were no apiVersions found that match our records.
I0501 10:38:38.954169 1267123 root.go:209] retCode: 0
```

However works fine on a Deployment:

```
cat << EOF | pluto detect -      
apiVersion: apps/v1beta1             
kind: Deployment
EOF      

NAME   KIND         VERSION        REPLACEMENT   REMOVED   DEPRECATED  
       Deployment   apps/v1beta1   apps/v1       true      true 
```

Is this expected? am I holding it wrong? or is it a bug?
