Description of problem:

In OpenShift 4.10, Kubernetes Services are [valid sink resources during Event Source creation](https://developers.redhat.com/articles/2022/03/22/whats-new-developers-openshift-410-console#openshift_4_10_serverless_and_eventing_features) - however, the generated `ContainerSource` resource sets `.spec.apiVersion` to `core/v1` instead of `v1`.

This results in the `SinkBinding` failing to generate the URI to the sink.



How reproducible:
Yes

Steps to Reproduce:
1. Install OpenShift Serverless on OpenShift 4.10.11 (RHPDS OpenShift 4.10 Workshop) and setup Knative Serving and Knative Eventing

2. Create a `Deployment` and `Service` that listens for CloudEvents - 

3. In the OpenShift console,
  a. Select Add / Eventing / EventSource / ContainerSource / Create Event Source
  b. Set the Image field to something that sends CloudEvents - I used `ghcr.io/kwkoo/fast-ping`
  c. Set the Input Target field to Resource and point it to the `event-display-deploy` Service
  d. Click Create

4. When you look at the generated `SinkBinding`, you get:

```
...
spec:
  sink:
    ref:
      apiVersion: core/v1
      kind: Service
      name: event-display-deploy
      namespace: demo
  subject:
    apiVersion: apps/v1
    kind: Deployment
    name: fast-ping-deployment
    namespace: demo
status:
  conditions:
    - lastTransitionTime: '2022-05-06T05:24:28Z'
      message: 'URI could not be extracted from destination '
      reason: NoURI
      status: 'False'
      type: Ready
```

5. It only works if you change `.spec.sink.ref.apiVersion` in the `ContainerSource` to `v1`
