Porting CustomHelpCommand from bot

[purefunctor]

Description

This proposes porting the CustomHelpCommand class from the server's Python Bot. This would mean either replacing the current implementation for SeasonalBot or extending it to fit the port.

Reasoning

Most command groups often make use of ctx.send_help like .snake or .cogs which don't utilize the help embeds. A common pattern that's used for this instead is to use ctx.invoke the help command explicitly like .caesarcipher. This would allow for the help responses for these command groups to be consistent with each other.

Proposed Implementation

The port should hopefully be a one-to-one copy of the original implementation, moving helper functions and adding a few adjustments for SeasonalBot.

Would you like to implement this yourself?

• I'd like to implement this feature myself
• Anyone can implement this feature

@purefunctor are you still planning on implementing this, or do you think this is worthy of more discussion?

[purefunctor]

I can't say I can work on this for now; I suppose further discussion might be needed in terms of the implications towards complexity or feature parity with the other bot.

[Xithrius]

Thank you for the quick response. I hope everything works out in the end.

This is now being ported to bot-core so that both bots can use the same code.

I'll take care of this.
