We would like to request adding a document loader for Bluesky, a decentralized microblogging social platform built on the AT Protocol.

Motivation

Bluesky has recently been rapidly increasing in popularity. As such, this integration allows users to use this document loader to get posts, replies, and threads from specific user handles, giving users the ability to summarize and filter these posts.

Proposal (If applicable)

If this idea is approved my team and I would like to work on it, and we hope to submit a PR by mid-November.
