helm lint does not work since helm v3.7.0

[clemcvlcs]

helm v3.7.0 broke helm lint when leading dash are set at top of yaml document
cf helm/helm#10149 (comment)

$ helm lint helm
engine.go:180: [INFO] Fail: feature key file not provided!
==> Linting helm
[ERROR] templates/clusterrole.yaml: unable to parse YAML: invalid Yaml document separator: apiVersion: rbac.authorization.k8s.io/v1

[ERROR] templates/serviceaccount.yaml: unable to parse YAML: invalid Yaml document separator: apiVersion: v1

Error: 1 chart(s) linted, 1 chart(s) failed

Removing leading dashs for clusterrole.yaml, clusterrolebinding.yaml, serviceaccount.yaml solves this issue
