Was the -Namespace parameter changed to -NamespaceName in Az.ServiceBus? I can't find a migration guide.

### Description

In Az.ServiceBus, we have a lot of scripts that use -Namespace as the parameter to them.

(Get-AzServiceBusQueue -ResourceGroupName $resourceGroup -Namespace $namespace,
Get-AzServiceBusTopic -ResourceGroupName $resourceGroup -Namespace $namespace,
etc.)

I noticed a release from 2 days ago. Was there a breaking change made to modules that use -Namespace instead of -NamespaceName? Which commands does this impact? I'm seeing signs that it might not just be the servicebus commands.

### Script or Debug output

```PowerShell
##[error]Parameter cannot be processed because the parameter name 'Namespace' is ambiguous. Possible matches include: -NamespaceName -NamespaceInputObject.

##[debug]System.Management.Automation.ParameterBindingException: Parameter cannot be processed because the parameter name 'Namespace' is ambiguous. Possible matches include: -NamespaceName -NamespaceInputObject
```

### Environment data

```PowerShell

```

### Module versions

```PowerShell
Az.ServiceBus 4.0.0
```

### Error output

```PowerShell
Parameter cannot be processed because the parameter name 'Namespace' is ambiguous. Possible matches include: -NamespaceName -NamespaceInputObject.
```

Start with the Az.ServiceBus 4.0.0 parameter definitions for Get-AzServiceBusQueue, Get-AzServiceBusTopic, and the other commands using Namespace. Determine whether Namespace was replaced, identify every affected command, and document the migration guidance and corrected parameter names.
