Reorganized SideStore commands to use a group structure, added individual subcommands for troubleshooting topics, and updated the help command to provide a dropdown for specific issues. This improves command discoverability and user experience.
Converted individual sidestore command cogs into functions and grouped them under a new Sidestore GroupCog in cogs/sidestore/__init__.py. Updated bot.py and help.py to recognize the new 'sidestore' category. This simplifies command registration and improves maintainability.
