patch undefined: Updated the DNS configuration in the resolv.conf.j2 template to include both the local host and the Ansible-managed DNS server.

Added a new line to the `resolv.conf.j2` template to specify the Ansible-managed DNS server (`{{ addc_ansible_host }}`). This ensures that the system uses both the local host and the managed DNS server for DNS resolution.
