Describe the bug

A clear and concise description of what the bug is.

To Reproduce

Steps to reproduce the behaviour:

1. install a helm release manually with some extra values:

helm get values sig-app                        
image:
  pullPolicy: Always
  repository: docker.pkg.github.com/myorgxxx/docker-repo/sign-org-api
  tag: 0.0.5
imagePullSecret: github-pull
ingress:
  enabled: false
probe:
  liveness: /api/health/live
  readness: /api/health/ready
replicaCount: 2
runmigration: false
service:
  monitor: false
  type: ClusterIP

2. Provide a HelmRelease
   sig-app-release.yaml:

---
apiVersion: helm.fluxcd.io/v1
kind: HelmRelease
metadata:
  name: docu-wrapper
  namespace: docu-wrapper
  annotations:
    fluxcd.io/automated: "true"
    fluxcd.io/tag.chart-image: semver:~0.0
spec:
  releaseName: docu-wrapper
  resetValues: false
  forceUpgrade: false
  chart:
    git: git@github.com:myorgxxx/helm_charts.git
    path: java
    ref: master
  values:
    image:
      repository: docker.pkg.github.com/myorgxxx/docker-repo/sign-org-api
      pullPolicy: Always
      tag: 0.0.7
  rollback:
    enable: true
    wait: true

3. Post the HelmRelease status, you can get this by running kubectl describe helmrelease <name>

kubectl get hr -A

kubectl describe hr -n docu-wrapper docu-wrapper

To not reset the old values

Now everything is up and running, Let me try to push a new image to my registry:
Logs

docker push docker.pkg.github.com/myorgxxx/docker-repo/sign-org-api:0.0.8

helm get values docu-wrapper                                                           
image:
  pullPolicy: Always
  repository: docker.pkg.github.com/myorgxxx/docker-repo/sign-org-api
  tag: 0.0.8

kubectl get pods -n docu-wrapper | grep Imag
docu-wrapper-java-fc8c545c7-xphgz   0/1     ImagePullBackOff   0          4m21s

old values are begin removed and without credentials the image pull doesn't works
