`az servicebus georecovery-alias show` is missing required parameters

[az servicebus georecovery-alias show](https://docs.microsoft.com/en-us/cli/azure/servicebus/georecovery-alias?view=azure-cli-latest#az_servicebus_georecovery_alias_show) mistakenly lists no required parameters.

From what I've seen, you have two ways you can use this command:
- `--resource-group`, `--namespace-name`, and `--alias` (as shown in the examples).
- `--ids` (no example provided)
- An example like `az servicebus georecovery-alias show --ids /subscriptions//resourceGroups//providers/Microsoft.ServiceBus/namespaces//disasterRecoveryConfigs/` would be useful.
