Cover Kotlin as Code examples for the SDK's

[JeromeK13]

Problem

The more coverage of the Documentation we do with the SDK's. The easier it is for future developers to start off.

Solution

Add examples for kotlin, which does not require its own SDK. Kotlin is fully compatible with Java.
Would bring some readable examples also with a focus on the android community. Where kotlin is the preferred language to write apps

Alternatives

There is more effort needed when the JAVA-SDK updates to also update the Kotlin example. But I don't think this is a big of a hustle
