silverwind 0ee4643d4a fix: install nftables in dind images to silence nft cleanup errors (#1064)
Fixes: https://gitea.com/gitea/runner/issues/1061
Related: https://github.com/moby/moby/pull/52886

Docker 29.6.0 changed `dockerd` to shell out to the external `nft` binary for firewall-rule cleanup instead of linking `libnftables` (release note: *"Mitigate a crash in libnftables when using nftables as the firewall backend by changing the default build option to execute the `nft` command instead."*). The upstream `docker:dind` image only ships `iptables`/`ip6tables`, so `dockerd` logs `failed to find nft tool` on startup and shutdown.

Networking is unaffected (default firewall backend is still iptables), but the errors are noisy. Install `nftables` in both dind variants to provide the binary.
