Service workflow-controller includes image digest in app.kubernetes.io/version label

[nushemto]

Describe the bug

My values:

# tried setting the images.tag but it didn't help
#images:
#  tag: v3.5.0
controller:
  serviceLabels:
    app.kubernetes.io/version: "v3.5.0". # this is a workaround, it creates an additional same-key label and sets the "v3.5.0" without the digest. Without this, the label's value appears with the digest.
    testing: "1234"
  image:
    registry: 1234.dkr.ecr.us-west-2.amazonaws.com
    repository: third-party/argoproj/workflow-controller
    tag: v3.5.0@sha256:dda36f7a872f463a68df04d72755c086eb193fa1645e1f099f1670dd5f99a277
  metricsConfig:
    enabled: true
server:
  image:
    registry: 1234.dkr.ecr.us-west-2.amazonaws.com
    repository: third-party/argoproj/argocli
    tag: v3.5.0@sha256:608b6d532b6a1ad4ae82b1e05ee844eb2f4fffe90a8524421f95e9355a7e4be1
  secure: true

When rendering the chart the result is that the label app.kubernetes.io/version in workflow-controller is using controller.image.tag instead of the Chart app version.

I am not sure why, but only the workflow-controller Service is specifying that label in this way. See here

Helm chart version

3.5.0

To Reproduce

1. Create a custom values file with the values I've shared above.
2. Run helm template -f custom-values.yaml .
3. Search for the kind: Service created for the workflow-controller and check its app.kubernetes.io/version label.

Expected behavior

Not to include the (full) image tag+digest as part of the label, only the Chart's App version, as is the case with all other resources.
