provisioning on hetzner with no IPV4 fails

[6543]

if WOODPECKER_HETZNERCLOUD_PUBLIC_IPV4_ENABLE=false is set, no agent task is provisioned on the host

I guess that's related to not working dual-stack setup for the docker engine (assuming the server can be reached via Ipv6).

the idea behind: ipv4 cost us ipv6 don't :)

Makes sense, in addition to the docker engine as mentioned above, the networks dynamically created by Woodpecker for each workflow need to be IPv6 enabled as well.
