I cannot add reviewers but this looks like a good update to

• The version of kotlin
• Targeting compileSdkVersion 33 which will be required for all new apps soon
• Migration to applicationId in build.gradle and away from packageId in AndroidManifest
• Updates to AGP and Gradle to the minimum supported versions by the next version of AndroidStudio Flamingo due to be released soon.
