Add comprehensive tests for Go and Python version conflict detection and licensing normalization

- Implemented GoVersionConflictDetectorTests to validate pseudo-version detection, conflict analysis, and conflict retrieval for Go modules.
- Created VersionConflictDetectorTests for Python to assess conflict detection across various version scenarios, including major, minor, and patch differences.
- Added SpdxLicenseNormalizerTests to ensure accurate normalization of SPDX license strings and classifiers.
- Developed VendoredPackageDetectorTests to identify vendored packages and extract embedded packages from Python packages, including handling of vendor directories and known vendored packages.
