Executor Helm Chart - kubernetesJob.node.tolerations doesn't render as expected

When setting the value for executor.kubernetesJob.node.tolerations it does not render in the configmap in the way that the executor pod is able to consume it.

I'm finding that if you set the following as the chart suggests:
tolerations: [{"key": "foo", "operator": "Equal", "value": "bar", "effect": "NoSchedule"}]
It will render as EXECUTOR_KUBERNETES_NODE_TOLERATIONS: map[effect:NoSchedule key:foo operator:Equal value:bar]
Causing your executor pod to throw invalid EXECUTOR_KUBERNETES_NODE_TOLERATIONS, failed to parse: invalid character 'm' looking for beginning of value into the logs and does not execute jobs.

If you do a manual edit of the configmap back to the original Json specified in the chart, then the jobs executor and respect the tolerations.

I think the chart is incorrectly trying to render the json to yaml, when it should remain as json.
https://github.com/sourcegraph/deploy-sourcegraph-helm/blob/main/charts/sourcegraph-executor/k8s/templates/executor.ConfigMap.yaml#L26

Untersuche charts/sourcegraph-executor/k8s/templates/executor.ConfigMap.yaml in Zeile 26 und den Wert für tolerations in charts/sourcegraph-executor/k8s/values.yaml etwa in den Zeilen 116–117. Rendere das Chart mit dem dokumentierten tolerations-Wert und vergleiche die ConfigMap-Ausgabe mit dem JSON, das der Executor erwartet. Als erledigt gilt die Aufgabe, wenn der Wert von EXECUTOR_KUBERNETES_NODE_TOLERATIONS weiterhin gültiges JSON ist und der Executor ihn parsen kann.
