### Description of the change Fix a wrong reference to `signing.existingKey`, `signing.existingSecret` was what was meant and what is used in the chart. ### Benefits Less confusion when trying to use the Helm chart. ### Possible drawbacks Evangelists of `existingKey` storming the barricades even though `existingKey` is long dead. ### Applicable issues None, nobody noticed enough to care, apparently.
