refactor(general): commands into GroupCog

Migrated general commands (ping, uptime, botinfo, serverinfo, feedback) into a single GroupCog in cogs/general/__init__.py for better organization and maintainability. Converted individual command files to export command functions instead of Cogs. Updated bot.py to load the new general extension. Renamed help.py for consistency.
