feat: add moderation commands and update README

- Introduced a new set of moderation commands including `/moderation purge`, `/moderation timeout`, `/moderation kick`, `/moderation ban`, `/moderation unban`, `/moderation untimeout`, and `/moderation slowmode`.
- Updated README to include details about the new moderation features and commands.
- Enhanced help command to display moderation tools and their usage.
