[stable/cockroachdb] adds resources stanza to cockroach init pod (#14921)

Browse Source 
Previously, this chart was not deployable in a Kubernetes namespace with
[Resource Quotas](https://kubernetes.io/docs/concepts/policy/resource-quotas/)
enabled. A user could set resource limits on the CRDB pods, but not on the
short-lived pod that is part of the cockroachdb-init job. This adds an
additional resource configuration to that pod spec to allow this chart to be
deployed when Resource Quotas are enabled.
