The upstream anubis2 theme references hugo.Data.social.social_icons,
but `hugo` is a build-info namespace (hugo.Version, etc.) and has no
.Data field — Hugo errors with "can't evaluate field Data in type
interface {}". Theme data files live under site.Data, so this override
swaps the access path. Submodule left untouched.
