When we update a document, the CID changes. We should probably update the Bluesky post's embed; though, maybe not? Currently, their AppView is seemingly idempotent. I've successfully updated a post before to fix a bug in a code snippet, and even though the replies remained link the reply count, view count, etc., reset (not that I care, but noticed it).
Thoughts? It's not like it's hard to do, but more a question of whether we should.
If it's not too much lift I don't see a reason not to. Even if bsky doesn't re-index changes like that other clients may!
