Sway and WayVNC support

Browse source 
- Added WayVNC configuration options for better security and usability.
- Updated echo statements to reflect the use of Sway instead of Weston.
- Improved kernel parameter check for 'nomodeset' with a warning message.
- Refined package installation steps to include necessary components for Sway.
- Configured Sway and greetd for autologin and session management.
- Added detailed instructions for troubleshooting and final checks.
