style 💎: Update debug message with correct variable usage

Fixed a typo in the debug message, updating it to use the correct variable `samba_domain_info.adminpass` instead of `addc_admin_password`. This ensures accurate output and prevents potential errors. The updated code will now correctly display the admin password for Samba AD DC.
