invalid document separator: ---apiVersion: networking.k8s.io/v1

Hi!

I am using the Helm Chart on version devlake@1.0.3-beta9 with the values.yaml as seen below:

```yaml
grafana:
grafana.ini:
server:
root_url: "https://devlake.example.com/grafana"
lake:
encryptionSecret:
secretName: devlake
autoCreateSecret: false
ingress:
enabled: true
enableHttps: true
useDefaultNginx: false
className: devlake-nginx
hostname: devlake.example.com
annotations:
cert-manager.io/cluster-issuer: google-ca
tlsSecretName: "devlake-tls-cert"
```

When rendering the chart and I get following error message:

`error merging manifests: parsing devlake/templates/ingresses.yaml: invalid document separator: ---apiVersion: networking.k8s.io/v1`

After looking at the Helm Chart templates, in the `ingresses.yaml` file, this section seems to be the culprit:

```yaml
---
{{- if semverCompare ">=1.19-0" .Capabilities.KubeVersion.GitVersion -}}
apiVersion: networking.k8s.io/v1
{{- else if semverCompare ">=1.14-0" .Capabilities.KubeVersion.GitVersion -}}
apiVersion: networking.k8s.io/v1beta1
{{- else -}}
apiVersion: extensions/v1beta1
{{- end }}
```

The usage of `{{-` and `-}}` seems to cause the whitespace (which includes newlines) to be remove and the resulting apiVersion gets generated right on the side of the `---`.

Start with devlake/templates/ingresses.yaml and inspect the Helm whitespace-trimming markers around the document separator and Kubernetes apiVersion condition. Render the chart using the reported values and Kubernetes version, then verify that the generated manifest has a valid separator before apiVersion and that the rendering error is gone.
