[BUG] Wrong response format from `WebApps_ListConnectionStrings` for Function App On ACA

[WebApps_ListConnectionStrings](https://github.com/Azure/azure-rest-api-specs/blob/98a8d5960798aca50fb816ab67e8ec9e1167abad/specification/web/resource-manager/Microsoft.Web/stable/2023-01-01/WebApps.json#L1926) returns `properties` as object `array` for Function App on Azure Container Apps(Centauri Function App). Though in Swagger, it's defined as object.

Response:
```json
{
"id" : "/subscriptions/REDACTED/resourceGroups/javacsmrg85739add/providers/Microsoft.Web/sites/java-function-74399/config/connectionstrings",
"name" : "connectionstrings",
"type" : "Microsoft.Web/sites/config",
"location" : "East US",
"tags" : { },
"properties" : [ ]
}
```

Swagger definition:
https://github.com/Azure/azure-rest-api-specs/blob/98a8d5960798aca50fb816ab67e8ec9e1167abad/specification/web/resource-manager/Microsoft.Web/stable/2023-01-01/WebApps.json#L24420-L24429

Start in specification/web/resource-manager/Microsoft.Web/stable/2023-01-01/WebApps.json at WebApps_ListConnectionStrings and the definition around lines 24420-24429. Compare the documented properties schema with the supplied Function App on Azure Container Apps response, then validate that the specification represents the observed response format.
