Missing Opengraph anf twittercard meta in head

[bugsysop]

Sample meta needed by OG/TC (inspiration from last Pleroma FE on Pleroma and Akkoma):

<meta content="User Name (@[email protected])" property="og:title">
<meta content="https://instance.tld/notice/AQy5HFd8rG1QfKfF3o" property="og:url">
<meta content="Post content... blah blah" property="og:description">
<meta content="article" property="og:type">
<meta content="https://instance.tld/43b3f048b7008327659dad5d.jpg" property="og:image">
<meta content="User Name (@[email protected])" name="twitter:title">
<meta content="Post content... blah blah" name="twitter:description">
<meta content="https://instance.tld/43b3f048b7008327659dad5d.jpg" name="twitter:image">
<meta content="summary_large_image" property="twitter:card">

This is the OG/TC meta for a status, but there are also version for user page and instance home.

Note: is correctly displayed with recent Soapbox.
