fix apps DeploymentSpec conversion issue
**What this PR does / why we need it**:
When working on #49645, I found current conversion for `v1.PodTemplateSpec` to `api.PodTemplateSpec` did not work properly. It should function as [L244-L246](https://github.com/kubernetes/kubernetes/blob/master/pkg/apis/apps/v1beta1/conversion.go#L244-L246).
