fix(helm): correct invalid ConfigMap template

[erikgb]

This corrects a bug in #142. Without this fix, the Helm chart rendering is erroring out with:

Error: Error: template: accurate/templates/deployment.yaml:18:28: executing "accurate/templates/deployment.yaml" at <include (print $.Template.BasePath "/configmap.yaml") .>: error calling include: template: accurate/templates/configmap.yaml:24:20: executing "accurate/templates/configmap.yaml" at <.Values.controller.config.propagateLabelKeyExcludes>: can't evaluate field Values in type []interface {}

Sorry for this, but this is a blocking error that will require a new patch release (of the Helm chart, at least).
