'helm template' command results in a newline character being stripped

[mrjgreen]

Bug
Running the helm template command with helm v2 can result in whitespace being removed, invalidating the helm chart.

The output of range templates inserver-service.yaml and server-deployment.yaml results in:

---apiVersion: v1
kind: Service

instead of

---
apiVersion: v1
kind: Service

See this issue with Cadence template for more detail: helm/helm#7149

To Reproduce

1. Using any helm 2.x
2. Run helm template

Expected behavior
Helm should not strip whitespace.

Screenshots/Terminal ouput

Versions (please complete the following information where relevant):

• OS: mac
• Temporal Version 1.9.2
• using Kubernetes and helm v2

Additional context

I think this could be fixed by changing:

{{- range $service := (list "frontend" "history" "matching" "worker") }}
{{- $serviceValues := index $.Values.server $service -}}

to

{{- range $service := (list "frontend" "history" "matching" "worker") }}
{{- $serviceValues := index $.Values.server $service }}

which will not remove whitespace.

I'm not sure if this will have any unintended impact
