Deserialization fails for com.microsoft.azure.ExpressionEvaluationDetails class

[petr-lindovsky]

The ExpressionEvaluationDetails class (https://github.com/Azure/autorest-clientruntime-for-java/blob/a869a9a68d5730e76a469bbe10d0e83b1a5532e3/azure-client-runtime/src/main/java/com/microsoft/azure/ExpressionEvaluationDetails.java) defines targetValue as List<String> but when calling

PUT https://management.azure.com/subscriptions/{subscriptionId}/resourcegroups/{resourceGroupName}?api-version=2021-04-01

we see response bodies where targetValue is a String, which causes deserialization failures.

Please fix the class to cover such response bodies.

Example exception:

com.fasterxml.jackson.databind.exc.MismatchedInputException: Cannot deserialize instance of `java.util.ArrayList<java.lang.Object>` out of VALUE_STRING token
