Discord.py hardcoded help command but it's better

hardhelp.py

@bot.command()
async def help(ctx: commands.Context, *, name: str = None):

    name = name.strip()

Here's a version of this command subclassed under commands.HelpCommand

which is ironically a better version than the original one since this version shows the subcommands of the asked group

(for the ones who aren't the type of ppl to "doing things the way they are not intended to")

bot.help_command = HelpCmd()

I didn't test this lmao
