Can we also remove exiting redirect root now?

sylius_admin_root:
    path: /
    defaults:
        _controller: FrameworkBundle:Redirect:redirect
        route: sylius_admin_dashboard
        permanent: true

@michalmarcinkowski is it connected to this PR? I have only adjusted a firewall.

@michalmarcinkowski shouldn't we put dashboard at / now?

Thanks Łukasz! 👍

The admin root can be adjusted in a separate PR. Not sure why it was under /dashboard at the first place. Let's wait with this change for @pjedrzejewski.
