Imperative examples could use some updating

* crossplane version: `v1.6.2`
* aws-provider: `v0.23.0`
* Provider can be easily installed with:
* `kubectl crossplane install provider crossplane/provider-aws:v0.23.0`

* In the `composition.yaml`:
* `kind: ElasicIP` should be replaced with `kind: Address`
* and `apiVersion: ec2.aws.crossplane.io/v1alpha1` should be replaced with `apiVersion: ec2.aws.crossplane.io/v1beta1`

* To get mine working, I also pointed
`crossplane.yaml`
at the upstream container image:

```yaml
dependsOn:
- provider: crossplane/provider-aws
version: ">=v0.20.0"
```

Inspect the composition.yaml and crossplane.yaml examples, then compare their provider kinds, API versions, and dependency image with the versions described in the issue. Done means the examples use Address with the v1beta1 API and point the dependency at the upstream provider image; no test or validation command is mentioned.
