Replace doesn't have line: to my knowledge.

So, to check I created a little test with my regexp to see if it work, and it
does.
$ more dns.yaml
network:
ethernets:
enp0s3:
addresses: [10.10.50.0/24]
gateway4: 10.10.50.5
dhcp4: no
nameservers:
addresses: [10.1.2.3, 10.1.2.4]
version: 2
$ cat test.yml
---
- hosts: localhost
vars:
dns1: 1.1.1.1
dns2: 2.2.2.2
gather_facts: no
tasks:
- replace:
path: dns.yaml
regexp: '(.*nameservers.*$\n.*addresses:).*$'
replace: '\1 [{{ dns1 }}, {{ dns2 }}]'
$ ansible-playbook test.yml

So it does work in my test.
