refactor(miscellaneous): cogs to command functions

Converted individual miscellaneous cogs (keanu, labubu, piracy, rickroll, tryitandsee) from class-based to function-based command definitions. Added a new __init__.py to group these commands under a single Miscellaneous GroupCog for easier management and setup.
