Pull Request Overview
This PR introduces new integration tests for Maven-based Java projects that verify the handling of different Java version configurations and compilation scenarios. The tests ensure that CodeQL's database creation works correctly across various Java version setups.
Key changes:
- Added four new Maven integration test projects to validate Java version handling
- Created test cases for multimodule projects with different Java versions per module, module flags (--add-exports), execution-specific Java versions, and Java 8 projects with Java 11+ dependencies

Missing space after comma in 'e.g.,records'. Should be 'e.g., records' with a space after the comma.
