Bump version of Kotlin Result to work around build failures

On a clean checkout,

./gradlew clean build

fails quite quickly with errors like the following:

> Task :core:support:compileKotlin FAILED

I don't totally understand the mechanism for why, but bumping the version of michael-bull kotlin-result to the latest version fixes the issues. Being on the latest version may have other advantages.
