Code Review

This pull request updates TiDB documentation for v8.5.6 and v9.0.0, transitioning background task management to GA and introducing tidb_slow_log_rules and tidb_slow_log_max_per_sec for advanced slow query filtering. It also documents FOR UPDATE OF enhancements, the new tidb_max_dist_task_nodes variable, and updated sync-diff-inspector installation methods. Feedback focuses on style guide compliance by using the second person, improving readability through list formatting, and ensuring descriptions are concise and complete.
