[BUG] The definition of AppService in Swagger is inconsistent with the value returned by the Service.

### API Spec link

https://github.com/Azure/azure-rest-api-specs/blob/0d9b77817effe915b68e20d1a1830bf3b682cbd3/specification/web/resource-manager/Microsoft.Web/AppService/stable/2021-02-01/WebApps.json#L4764

### API Spec version

2021-02-01

### Describe the bug

There is two customer issue related:
https://github.com/Azure/azure-sdk-for-net/issues/50743
https://github.com/Azure/azure-sdk-for-net/issues/37585
Request:
GET /subscriptions/<>/resourceGroups/<>/providers/Microsoft.Web/sites/<>/hybridconnection/<>?api-version=2021-02-01
Response:
{"id":"sdktest456","name":"Microsoft.Web/sites","type":"East US"}
The Type here is mismatch for resourceType. Or the whole response is incorrect.

### Expected behavior

{"id":"","name":"sdktest456","type":"Microsoft.Web/sites","location":"East US"}

### Actual behavior

{"id":"sdktest456","name":"Microsoft.Web/sites","type":"East US"}

### Reproduction Steps

Request:
GET /subscriptions/<>/resourceGroups/<>/providers/Microsoft.Web/sites/<>/hybridconnection/<>?api-version=2021-02-01

### Environment

_No response_

从 specification/web/resource-manager/Microsoft.Web/AppService/stable/2021-02-01/WebApps.json 第 4764 行开始，将 AppService 定义与已记录的请求和响应进行比较。查看链接的 azure-sdk-for-net issues 以了解上下文，然后验证预期和实际的 payload 形状；当 specification 准确匹配 service response，或差异已得到澄清时，即表示完成。
