Is your feature request related to a problem? Please describe.
I was looking to find a way to show command help during execution of a command. For example, I have main command of cli set to display fidglet text. But I want to show command help right after.

Describe the solution you'd like
Ideally, having a function in AnsiConsole or CommandContext to render command help. For example

public override int Execute(CommandContext context)
{
   AnsiConsole.WriteHelp();
}

I am not sure if there exists a function to provide such implementation. If there is, please refer me to that.
