Fix versionCode parameter extraction in DistributionIntegration

- Extract versionCode properly from PackageInfo using longVersionCode for API 28+
- Fall back to deprecated versionCode for older Android versions
- Add missing mainBinaryIdentifier parameter to UpdateCheckParams constructor
- Use proper API-level checks to avoid deprecation warnings

This resolves the compilation error where 'version' was undefined.
