[Java] Replace Maven Central with Azure Artifacts feed in automation scripts

- Updated MAVEN_HOST in parameters.py to use Azure Artifacts feed URL
- Added SYSTEM_ACCESSTOKEN Bearer auth headers to requests in utils.py
  and generate_utils.py for CI environments
- Added timeout=30 to all requests.get() calls missing timeouts
- Exposed SYSTEM_ACCESSTOKEN env var in generation.yml pipeline steps
