Remove unused values from helm chart (#2470)

* chore: remove unused servicemonitor-values from helm-chart

The templates for the servicemonitors of the webhook-deployment and the
certController have been removed in
https://github.com/external-secrets/external-secrets/pull/2136. This
commit removes the corresponding values in the values.yaml which are now
obsolete.

 If you are using a different monitoring tool that also needs a `/metrics` endpoint, you can set the `metrics.service.enabled` Helm flag to `true`. In addition you can also set `webhook.metrics.service.enabled` and `certController.metrics.service.enabled` to scrape the other components.
