Subject: [PATCH] Update index.json to include date_modified

This uses Hugo's [.Lastmod](https://gohugo.io/methods/page/lastmod/) to add the optional property of JSON Feed 1.1 [date_modified](https://www.jsonfeed.org/version/1.1/) based on [Rick Cogley's request](https://help.micro.blog/t/add-date-updated-to-feed-json/2267/2).
