Fixed missing new version info in some hook environments

Introduce the `new_version_env` function and update existing functions (`get_setup_hook_env` and `get_pre_commit_hook_env`) to include new version environment variables. Added new tests for verifying the inclusion of OS, SCM, current, and new version information in hook environments.
