Creating a post with a duplicate rkey returns an internal server error rather than proper error handling.

[oracularhades]

Run this twice at /xrpc/com.atproto.repo.createRecord: {"collection":"app.bsky.feed.post","repo":"did:plc:wtdzzfgzjpirnk5wvpjutqoy","record":{"text":"another test post","langs":["en"],"createdAt":"2024-12-09T00:00:00.000Z","$type":"app.bsky.feed.post"}, "validate": false, "rkey":"theyre-called-skeets"}

You'll get a 500 internal server error instead of something like "rkey already exists". Not a major bug but definitely important to note for automated scripts.
