BUG: helmRepository value doesn't allow multiple values

Bug

Description

when using the Helm Wrapper chart and attempting to configure multiple HelmRepositories, an invalid Kubernetes manifest file is generated due to the range loop in this file: https://repo1.dso.mil/big-bang/bigbang/-/blob/master/chart/templates/helm-repository/helmreposecret.yaml?ref_type=heads

One way to solve this would be a check for the last iteration of the loop at the end. If it is not the last iteration, add a --- to separate the manifests.

This is what the generated file looks like:

---
# Source: test/templates/deployment.yaml
apiVersion: v1
kind: Secret
metadata:
  name: test
  namespace: default
type: kubernetes.io/dockerconfigjson
data:
  .dockerconfigjson: blah
apiVersion: v1
kind: Secret
metadata:
  name: test
  namespace: default
type: kubernetes.io/dockerconfigjson
data:
  .dockerconfigjson: blah

These are the values which will trigger this bug

helmRepositories:
    - name: blah-repo
      repository: oci://registry.gitlab.com/blah
      type: oci
      username: blah
      password: blah
    - name: blahblah-repo
      repository: oci://registry.gitlab.com/blahblah
      type: oci
      username: blahblah 
      password: blahblah
