Fix Service Bus part based on review

- [ ] SLA details needs to be updated. Premium AZ feature with partitions enabled has 99.99% SLA (page 78 in sla doc)
- [ ] Change the name of the "Capacity" column to "Messaging units" in the detail pane and summary pane to make the source clear
- [ ] Display number of Partition("premiumMessagingPartitions") as column

- Refer APRL
https://azure.github.io/Azure-Proactive-Resiliency-Library-v2/azure-resources/ServiceBus/namespaces/

- The following is result of ARG properties:
```json
{
"provisioningState": "Succeeded",
"publicNetworkAccess": "Enabled",
"status": "Active",
"minimumTlsVersion": "1.2",
"zoneRedundant": true,
"disableLocalAuth": false,

}
```

### memo
Currently, ARG does not support child resources such as queue and topic.

The following were considered but not obtained by ARG:
- can we also capture geo recovery feature is setup or not? not sure this is exposed in ARG
- Do we have ability to support partitioning as well?
- Can we check autoscaling?
