fix: enable forward by default for Fedora zones
    
    Upstream enabled forward [1] by default for stock zones in v1.0.0.
    FedoraServer and FedoraWorkstation should follow upstream. This fixes
    some out of the box issues for users.
    
    e.g. wireguard doesn't work until user does `firewall-cmd --add-forward`
    
    With this enabled wireguard and other VPNs will work out of the box.
