[kube-prometheus-stack] add extra dashboard in grafana parse error

[TOTom]

Describe the bug a clear and concise description of what the bug is.

hi, I want to add extra dashboard in the grafana deployed by kube-prometheus-stack. I found the file "kube-prometheus-stack/templates/grafana/configmap-dashboards.yaml" is used to load the configmap for the grafana dashboard. So I followed the code logic, and added a json file which is exported by the grafana in the "dashboards-1.14" directory, dry run. I got the error:

error log with dry run: install.go:200: [debug] Original chart version: "" install.go:217: [debug] CHART PATH: C:\Users\mauc\projects\tencent\iac\terraform\helm\kube-prometheus-stack
