Fix spelling for consistency (behaviour -> behavior)

Overview

Hi there.

I found behaviour and behavior are used in this repository. I think the spellings should be unified for consistency. 🤔

Makes sense.

It seems that you altered example files, can you run ./gradlew knit (https://github.com/Kotlin/kotlinx.serialization/blob/master/CONTRIBUTING.md#running-the-knit-tool) to re-generate documentation tests and commit the result?
