refactor(fun): cogs into one group

Combined all fun commands into a single 'fun' GroupCog with subcommands, replacing individual cogs for coinflip, eightball, minesweeper, randomfact, and rockpaperscissors. Updated bot.py to load the fun cog as a package and adjusted help.py to reflect the new command structure. This improves organization and discoverability of fun commands.
