Review meta: OpenGraph, JSON-LD, etc.

jekyll-seo-tag appears limited in flexibility and the best way may be to manually render meta tags and JSON.

OG tags that appear missing:

<meta property="og:url" content="" />
<meta property="og:image" content="" />

Extraneous tag:

<meta name="generator" content="Jekyll v3.8.3" />

JSON-LD issues:

Uses “Person” type as author even when referring to organization name as maintainer on project sites
Uses “WebSite” type globally. Another entity may be more appropriate depending on site type (open hub vs. open project)
