[solankisamir]

We need to publish DurableTask.ServiceBus nuget package to https://www.nuget.org/packages/Microsoft.Azure.DurableTask.ServiceBus

Need to make changes to Generate Nuget package in https://github.com/Azure/durabletask/blob/main/eng/templates/build.yml

The project file is https://github.com/Azure/durabletask/tree/main/src/DurableTask.ServiceBus. Please make sure to resolve any errors with build compilation.
