Add Werewolves Assistant API to readme list

[antoinezanardi]

I always try to make my README's easy and pleasant to read with clear sections, images, badges and more.

You can check it out here : antoinezanardi/werewolves-assistant-api-next - Feedbacks would be appreciated :)

Thank you @matiassingers for your time.
