Microsoft.Security/DefenderForStorageSettings: Missing malwareScanning property

### Resource Type

Microsoft.Security/DefenderForStorageSettings

### Api Version

2022-12-01-preview

### Issue Type

Missing property(s)

### Other Notes

Deployment works as expected but type checking claims the `scanResultsEventGridTopicResourceId` property is not allowed.

### Bicep Repro

```
resource defenderForStorageSettings 'Microsoft.Security/DefenderForStorageSettings@2022-12-01-preview' = {
name: 'current'
scope: ${storage_account}
properties: {
isEnabled: true
malwareScanning: {
onUpload: {
isEnabled: true
capGBPerMonth: 5000
}
scanResultsEventGridTopicResourceId: ${event_grid_topic_id}
}
sensitiveDataDiscovery: {
isEnabled: true
}
overrideSubscriptionLevelSettings: true
}
}

```
### Confirm

- [X] I have read the troubleshooting guide and looked for duplicates.

Start with the type definition for Microsoft.Security/DefenderForStorageSettings at API version 2022-12-01-preview and compare it with the Bicep repro. Update the definition so the shown malwareScanning properties, including scanResultsEventGridTopicResourceId, are accepted by type checking, then verify the repro deploys and type-checks successfully.
