Fixes #2072

Description
Clear and concise code change description.

Starting AGP 8.0, automatic component creation is disabled, meaning we need to explicitly configure our publication variant: https://developer.android.com/build/publish-library/configure-pub-variants

Tested:
Ran ./gradlew publishToMavenLocal and ./gradlew publishReleasePublicationToCIRepository and they both now work again :)
