very minor nit: capitalize CIPD and Gradle for consistency, where not being used as part of a command

This is not ready for review. I only have it up so that I can see what builds in ci.

FAILURE: Build failed with an exception.

• What went wrong:
  Could not determine the dependencies of task ':testDebugUnitTest'.

Could not create task ':processDebugManifest'.
Cannot use @TaskAction annotation on method IncrementalTask.taskAction$gradle_core() because interface org.gradle.api.tasks.incremental.IncrementalTaskInputs is not a valid parameter to an action method.

abandoning for more urgent work.
