- Added `GIT_TERMINAL_PROMPT` environment variable set to `0` to suppress terminal prompts during Git operations.
- Redirected standard input to null to prevent any interactive prompts, ensuring smoother initialization processes.

These changes aim to enhance the user experience by streamlining the Git initialization workflow.
