Wrong labels in topologySpreadConstraints example in the Helm chart values

[wallrj]

While working on https://github.com/cert-manager/approver-policy/pull/385 I noticed these new labels in the example are wrong. They are cert-manager labels.

https://github.com/cert-manager/trust-manager/blob/34bb21e768695b4503e8e831e99f5d5ffb53f441/deploy/charts/trust-manager/values.yaml#L137-L147

Check for other copy-paste errors when we fix this.
