scheduleUpdateTwin does not support module twin update

When user use modules, it is expected that the module twins need to be updated for a group of device modules.

From the code it looks like scheduleUpdateTwin() does not support updating module twin. How user will be able to update module twins without going through individual device modules? Is there a way?

Start by locating scheduleUpdateTwin() in the Java service SDK and reading its existing handling for device twins and modules. Determine whether grouped module-twin updates are supported by the exposed service API, then define the expected module input and completion behavior before changing the implementation. No specific file or test is named in the issue.
