Example for az connectedmachine upgrade-extension is inconsistent with documentation #34267

The inconsistency is in the action, upgrade-extension vs extension upgrade

Documentation shows this syntax:

az connectedmachine upgrade-extension [--acquire-policy-token]
[--change-reference]
[--extension-targets]
[--ids]
[--machine-name]
[--no-wait {0, 1, f, false, n, no, t, true, y, yes}]
[--resource-group]
[--subscription]

Example is:

az connectedmachine extension upgrade --machine-name "myMachineName" --resource-group "myResourceGroup" --subscription "mySubscription" --targets "{"Microsoft.Compute.CustomScriptExtension": "{"targetVersion": "1.10"}", "Microsoft.Azure.Monitoring": "{"targetVersion": "2.0"}"}"
