refactor: remove NSFW media detection

docs/changes.md

@@ -108,6 +108,8 @@
 
 ### 主要な変更点
 
+- センシティブなメディアの自動検出機能を削除
+  - 誤検知が多く、使っているサーバーもあまり多くないと思ったため（困る場合には教えてください）
 - 非ログインユーザーにもローカルタイムラインとグローバルタイムラインを公開できるように変更
   - コントロールパネルから設定すると `https://server.example.com/timeline` で公開されます
 - 全文検索のエンジンを [PGroonga](https://pgroonga.github.io/) に変更（[tamaina さんの PGroonga パッチ](https://gist.github.com/tamaina/29e88e02d0dc5acfa2f50b3347d3d20d)を拡張）
