feat(scripts): add IRC_ROOT_DOMAIN variable to configuration scripts

Add IRC_ROOT_DOMAIN to the prepare-config.sh script to display
its value or indicate if it's not set. Update ssl-manager.sh to
use IRC_ROOT_DOMAIN instead of IRC_DOMAIN for the DOMAIN variable.
This change allows for more flexibility and clarity in managing
domain configurations, especially when the root domain differs
from the IRC-specific domain.
