Kotlin 1.5 is incompatible with Gradle 8

[dereklucas]

After updating to Expo SDK 49 I found this plugin won't build for Android.
While building, it threw the error

@TaskAction annotation on method AbstractKotlinCompile.execute() because interface org.gradle.api.tasks.incremental.IncrementalTaskInputs is not a valid parameter to an action method.

After some research, it seems this is a conflict between Kotlin 1.5 and Gradle 8. Bumping this plugin's kotlin version to 1.6.0 fixed it.
I used patch-package to patch @amplitude/[email protected] to apply this diff:

If you'd like me to open a PR similar to #27 but narrowed to only the kotlin version, let me know.

@dereklucas Thanks! PR is always very much appreciated. I have a number of open issues on this SDK, so I'll add this to the backlog and try to get them all done at the same time.
