Update container resources reference link
**What this PR does / why we need it**:
Users are currently directed to documentation on `PersistentVolumeClaim` resources when looking for information on `Container` resources. While this field is backed by the same type in both instances, [Managing Compute Resources for Containers](https://kubernetes.io/docs/concepts/configuration/manage-compute-resources-container/) is more relevant in the `Container` context.
This is surfaced in at least two places:
- https://kubernetes.io/docs/reference/generated/kubernetes-api/v1.11/#container-v1-core
- `kubectl explain pod.spec.containers.resources`
**Release note**:
```release-note
NONE
