Update multicoloredline.py

- Migrated from `quo` to `rich` for better terminal output and functionality.  
- Added **syntax-highlighted JSON** output using `rich.syntax.Syntax.  
- Implemented **progress bar** with animated spinner using `rich.progress.Progress.  
- Introduced **structured table display** with `rich.table.Table` for system metrics.  
- Enhanced user feedback with a **completion success message**.  
- Improved readability and interactivity for a better terminal experience.
