modify fb postrenderers to fit all schema types

General MR

Summary

Removes the options key from the fluentbit postrenderer that was breaking Party Bus' schema.

Unsure why this is not an issue on our end, but the helmrelease works fine without it anyway.

Upgrade Notices

In release 8.0.10-bb.1, ArgoCD was migrated to the passthrough pattern. During this update, the argocd-apps key was incorrectly nested under upstream (i.e., .Values.upstream.argocd-apps) instead of being defined as a top-level key (i.e., .Values.argocd-apps).

This misplacement does not cause functional issues in the affected versions. However, to ensure proper value injection, configuration should be passed using the top-level argocd-apps key.

This issue has been corrected in Merge Request big-bang/product/packages/argocd#371
