council(nav): Import attributes partial to fix team name
    
    I used an attribute that was not imported into the AsciiDoc file, so the
    `{team_name}` attribute appeared literally instead of what it should
    have resolved to, which is "Fedora Council". This is now fixed and
    verified locally.
