Overwrite `to_info_dict()` method in `Context` and command classes

[wabiloo]

The click context object has a method .to_info_dict() that's useful to go through the whole CLI structure, for example to write documentation.

It would be good to have an equivalent with cloup, so that all the other info cloup adds (eg. Aliases and help) can be exposed in the same way

Hi! This method seems to exist to generate a JSON representation of the CLI to be consumed by external tool. Do you know any of these external tool that make use of it? Note that this method not really useful for traversing the CLI: by converting to dict, you lose type information and autocomplete, which can only worsen your DX.

Anyway, you're welcome to contribute!

This one does, which creates an auto-complete for Fig: https://github.com/withfig/autocomplete-tools/blob/main/integrations/click/click_complete_fig/fig.py

But as I played with it yesterday (after starting this thread), I came to the same conclusion and converted to traverse the click/cloup object model instead. Really not complex, and in 10 min, the conversion was done and now I also have access to all of cloup's info...

I'll keep this open for whoever wants to contribute.
