Description
Consider the following state:

basics-tcp-out22-send-ipv6:
    nftables.append:
        - table: filter
        - chain: output
        - family: ip6
        - jump: accept
        - destination: '::/0'
        - dport: 22
        - match: state
        - connstate: new
        - proto: tcp
        - save: True

This state would create a nftables rule that allows the box to connect to port 22 on every IPv6 address out there. However, nftables.build_rule creates the following nft call:

nft add rule ip6 filter output ct state { new } ip daddr ::/0 tcp dport { 22 } accept

which leads to the following error:

Error: conflicting protocols specified: ip6 vs ip

Steps to Reproduce the behavior
Spin up an ipv6 enabled box and try to apply the above state.

Expected behavior
The correct command would read:

nft add rule ip6 filter output ct state { new } ip6 daddr ::/0 tcp dport { 22 } accept
