Can't use output artifact with disabled archive in CronWorkflow

[remicres]

Pre-requisites

• I have double-checked my configuration
• I have tested with the :latest image tag (i.e. quay.io/argoproj/workflow-controller:latest) and can confirm the issue still exists on :latest. If not, I have explained why, in detail, in my description below.
• I have searched existing issues and could not find a match for this bug
• I'd like to contribute the fix myself (see contributing guide)

What happened? What did you expect to happen?

I am unable to use outputs: artifacts: archive: none: {} in CronWorkflow.
In Workflow everything works as expected.

Version(s)

v2.9.11+91bb155

Paste a minimal workflow that reproduces the issue. We must be able to run the workflow; don't enter a workflows that uses private images.

With Workflow: OK

Borrowed from the argo examples, and reduced to the minimum:

apiVersion: argoproj.io/v1alpha1
kind: Workflow
metadata:
  name: toto-wf
  namespace: cdos
spec:
  entrypoint: whalesay
  templates:
  - name: whalesay
    container:
      image: docker/whalesay:latest
      command: [sh, -c]
      args: ["cowsay hello world | tee /tmp/hello_world.txt | tee /tmp/hello_world_nc.txt ; sleep 1"]
    outputs:
      artifacts:
      - name: hello-txt
        path: /tmp/hello_world.txt
        archive:
          none: {}

With CronWorkflow: NOK

apiVersion: argoproj.io/v1alpha1
kind: CronWorkflow
metadata:
  name: toto-cron
  namespace: cdos
spec:
  schedule: 0 0 * * *
  workflowSpec:
    entrypoint: whalesay
    templates:
    - name: whalesay
      container:
        image: docker/whalesay:latest
        command: [sh, -c]
        args: ["cowsay hello world | tee /tmp/hello_world.txt | tee /tmp/hello_world_nc.txt ; sleep 1"]
      outputs:
        artifacts:
        - name: hello-txt
          path: /tmp/hello_world.txt
          archive:
            none: {}

We got:

cannot unmarshall spec: cannot restore struct from: slice

When we remove archive: None: {} or if we set another archive strategy it works fine.

### Logs from in your workflow's wait container

```text
kubectl logs -n argo -c wait -l workflows.argoproj.io/workflow=${workflow},workflow.argoproj.io/phase!=Succeeded

I am unable to get anything using this command (I tried to modify it to grab cronworkflows without success)

[Joibel]

The version you have given for your version of workflows is ancient (2.9...). Is that correct? If so, I would suggest upgrading to something supported (3.5.13 or 3.6.2) and trying again.

[remicres]

Yes I'll perform some tests as soon as we upgrade argo.
