IPv6 is not assigned

[lbrdt]

For the last couple of days, the action isn't able to assign IPv6 (and also IPv4) to the github runners, and connecting to IPv6 only services fail.

Here's a run

Run fscarmen/warp-on-actions@v***.***
  with:
    stack: dual
    mode: wireguard
Run if [ "wireguard" == 'client' ]; then
WARP mode: wireguard.
