Code Review

This pull request adds RuntimeClass and PodAnnotations to the VLLMRuntime custom resource and updates the controller to propagate these settings to the Deployment. The review feedback points out typos in the new API fields, specifically RunetimeClass and nividia, which should be corrected. Additionally, the reviewer advised against using reflect.DeepEqual for pod annotations to avoid infinite reconciliation loops caused by external controllers, recommending a subset-based comparison instead.
