Add Microsoft's Adaptive Cards

[karol-gro]

It'd be good to include Microsoft Adaptive Cards (https://learn.microsoft.com/en-us/adaptive-cards/getting-started/outlook) to described features

@karol-gro do you know if Microsoft thinks about Adaptive Cards / Actionable Messages becoming an industry standard, or to remain as a feature that is only available inside Outlook?

@michael-westphal They released source code on MIT license, they also added rendering in many other products (Teams, MS Bot
framework, Windows Timeline) and they released SDK to render the card in you own app on iOS, Android, in JS or in ReactNative. So it looks like they want to make it a standard
