fix(argo-workflows): Remove excessive wf controller RBAC permissions

[tico24]

The deleted privileges were used by the k8sapi Executor in older Argo Workflows versions <=3.3 when selected. In versions >=3.4, only the Emissary Executor is available, and it does not use any forms of elevated privileges. See also a summary of the Executors in an older version of the docs: https://argo-workflows.readthedocs.io/en/release-3.4/workflow-executors/.

So which version of Argo Workflows do we support? This change will break any versions < 3.4, as they need the pod permissions.

[tico24]

We have only ever supported the latest of each product. So workflows 3.6.0

For reference, this resolves the now public GHSA-fgrf-2886-4q7m (and the description seems to heavily copy from there as well) aka CVE-2024-52799
