'az maintenance assignment create-or-update-subscription' example does not work

### Describe the bug

I am trying to create a maintenance assignment using the example from the documentation as the template, but when I specify the example tags, the command outputs an error.

### Related command

The example is as follows:
`az maintenance assignment create-or-update-subscription --maintenance-configuration-id "/subscriptions/00000000-0000-0000-0000-00000000/resourcegroups/exmaplerg2/providers/Microsoft. Maintenance/maintenanceConfigurations/config1" --name assignmentname --filter-locations eastus2euap centraluseuap --filter-os-types windows linux --filter-tags "{{tagKey1:[tagKey1Val1,tagKey1Val2],tagKey2:[tagKey2Val1,tagKey2Val2]}}" --filter-tags-operator All`

I have attempted the following:
`az maintenance assignment create-or-update-subscription --config-id "/subscriptions/redacted/resourcegroups/redacted-rg-01/providers/Microsoft.Maintenance/maintenanceConfigurations/bc-test-delete-me" --configuration-assignment-name "REDACTED - Production" --subscription "REDACTED - Production" --filter-locations uksouth --filter-os-types windows linux --filter-tags "{{tagKey1:[tagKey1Val1,tagKey1Val2],tagKey2:[tagKey2Val1,tagKey2Val2]}}" --filter-tags-operator All`

### Errors

`Failed to parse '--filter-tags' argument: Shorthand Syntax Error: Redundant tail:
{{tagKey1:[tagKey1Val1,tagKey1Val2],tagKey2:[tagKey2Val1,tagKey2Val2]}}`

### Expected behavior

I would expect the tags to be added to the dynamic scope of the maintenance configuration.

Your CLI is up-to-date.

### Additional context

I have also tried a few other syntaxes for the --filter-tags switch:
`
--filter-tags "{updateRing:[1]}"
--filter-tags "{updateRing:1}"
--filter-tags "updateRing:1"
--filter-tags updateRing:1
--filter-tags updateRing:[1]
--filter-tags "{updateRing:[1],updateReboot:[never]}"
--filter-tags "{updateRing:1,updateReboot:never}"
--filter-tags "{{updateRing:[1],updateReboot:[never]}}"
`

None of theses efforts worked.
