https://opensource.org/blog Open Graph tags are wrong #173

Description

Hi team,

If you open /blog, the og: graphs are overwritten by Nelio with the ones from the latest post:

`
Nelio Content
meta property="og:locale" content="en_US"
meta property="og:type" content="article"
meta property="og:title" content="The OSI endorses the United Nations Open Source Principles"
meta property="og:description" content=""
meta property="og:url" content="https://opensource.org/blog"
meta property="og:site_name" content="Open Source Initiative"
meta property="og:image" content=""
meta property="og:image:width" content=""
meta property="og:image:height" content=""
meta name="twitter:card" content="summary_large_image"
meta name="twitter:creator" content=""
meta name="twitter:site" content=""
meta name="twitter:image" content=""
/Nelio Content

`

They should be static ones for /blog
