Pull request overview

This pull request updates the feature flag for repository properties from use_repository_properties to use_repository_properties_v2. This change allows the feature to be rolled out exclusively to CodeQL Action versions that include the improved error handling introduced in PR #3421. The feature flag name change is a versioning strategy to ensure only newer Action versions with better error tolerance will be able to enable the repository properties feature.

Changes:

• Updated the Feature enum value from "use_repository_properties" to "use_repository_properties_v2" in the TypeScript source
• Maintained backward compatibility by keeping the enum name UseRepositoryProperties and environment variable CODEQL_ACTION_USE_REPOSITORY_PROPERTIES unchanged
• Generated JavaScript files in lib/ directory reflect the TypeScript changes
