examples_automation, adopt change of java release tag

Pull request overview

This pull request adapts the Java examples automation tooling to support a new release tag format that includes the Maven group ID prefix. The new format uses com.azure.resourcemanager+azure-resourcemanager-storage_1.0.1-beta.1 while maintaining backward compatibility with the older format azure-resourcemanager-storage_1.0.1-beta.1.

Key Changes:

• Added a new get_package_name() function to strip the group ID prefix from package names
• Updated the regex pattern in configuration.json to match both old and new release tag formats
• Added unit tests for the new package name extraction function
