Gary Pendergast 63d9e9df96 Embeds: Provide a cached text fallback.
Sometimes, embedded sites might suffer from less than 100% uptime. Instead of leaving the embedding site with a big blank space where the embed should be, let's fall back to a link to the embedded post, so there's at least some context for the post.

Fixes #34462.
