Provide help message when --help is used in a cli with required arguments about rich-click

Hi @girivs82,

Thanks for creating the issue! I agree that --help feels like a special case 👍🏻

There are two ways that you can use rich-click - the simpler import rich_click as click or the more verbose declarative method (import click; from rich_click import RichCommand, RichGroup). There's an example of the latter in examples/02_declarative.py. This method is basically native click so you should be able to a similar workaround with this.

Longer term, I think it would be interesting in looking into whether we can implement this natively within rich-click. Any contributions along these lines would be welcome.

Thanks! I will try the declarative method and wait for any native implementation of this. I'll also look at the source to see if I can help contribute to this issue in some way.
