Issue:
XR schema should not have `status.crossplane.connectionDetails`
### What happened?

We dropped the ability to write connection secrets from XRs for https://github.com/crossplane/crossplane/issues/6440, with https://github.com/crossplane/crossplane/pull/6473 where we dropped `spec.crossplane.writeConnectionSecretToRef` from XRs.

We would expect the CRDs created for XRs to no longer have `status.crossplane.connectionDetails`, as this no longer makes sense given what was removed from the spec, yet they still do: https://github.com/crossplane/crossplane/blob/54e0ba1350bd0f234beb1a3beee2d605885f015b/internal/xcrd/schemas.go#L328-L333

### How can we reproduce it?

Create a XRD, for example the XRD from https://docs.crossplane.io/v2.0-preview/get-started/get-started-with-composition/#define-the-schema

Check the schema of the generated CRD, e.g. with `kubectl get crd apps.example.crossplane.io -o yaml`. The schema should not have this block under `status`:
```
              crossplane:
                description: Indicates how Crossplane is reconciling this composite
                  resource
                properties:
                  connectionDetails:
                    properties:
                      lastPublishedTime:
                        format: date-time
                        type: string
                    type: object
                type: object
```


### What environment did it happen in?
Crossplane version:  `2.0.0-rc.0.312.g26c45a568`
