fix(codeowners): name the outside collaborators on the enforcement paths

@mrunalp, @sjenning, and @derekwaynecarr are maintainers but not members
of @NVIDIA/openshell-codeowners, and as outside collaborators they cannot
join it. Owning these paths by team alone would have meant no Red Hat
maintainer could approve a change to the merge gate.
