[Bug Report] `userId` in live test response is `int32` but after sanitized the type become `string`

repro：

sdk: sdk\resourcemanager\storage\armstorage\storage_live_test.go

add [logging](https://github.com/Azure/azure-sdk-for-go/blob/main/documentation/development/ARM/new-version-guideline.md#logging) config in func `TestLocalUsers`
``` test code

// From step LocalUsers_CreateOrUpdate

Start with sdk\resourcemanager\storage\armstorage\storage_live_test.go and the TestStorageTestSuite.json recording, then run go test -run TestStorageTestSuite. Compare the live response's numeric properties.userId with its sanitized recording; done means the sanitized fixture preserves the correct response type without breaking the test.
