Bookmark for YouTube links not populated with video metadata

Issue Summary

Helloo!

When adding a /bookmark to a post using a YouTube video link, it fills the bookmark card with generic info rather than a card containing the video's metadata.

Recently, I tried this on v5.129.1 with Firefox & iOS Safari, then upgraded to v6.0.5 using ghost-cli, and tried again with both. But I've had it with earlier versions too.

If this is something silly that I've done rather than a bug, then no problem at all!

Video as a bookmark card vs an embed

Metadata from the youtube video's page

<meta property="og:site_name" content="YouTube">
<meta property="og:url" content="https://www.youtube.com/watch?v=0i1Xz-xiYSU">
<meta property="og:title" content="What happens in the European Space Agency's Mission Control?">
<meta property="og:image" content="https://i.ytimg.com/vi/0i1Xz-xiYSU/maxresdefault.jpg">
<meta property="og:image:width" content="1280">
<meta property="og:image:height" content="720">
<meta property="og:description" content="The European Space Agency invited me to their mission control centre in Germany to find out what it takes to be a Satellite Operations Engineer working on th...">
