Use gradle-build-action in starter workflows (#1237)

The `gradle-build-action` provides enhanced execution and caching functionality for Gradle.
This change updates starter workflows to use `v2.0.0` of `gradle-build-action`.

Improvements over invoking Gradle directly include:
- Easier to run the workflow with a particular Gradle version
- More sophisticated and more efficient caching of Gradle User Home between invocations
- Detailed reporting of cache usage and cache configuration options
- Automatic capture of Build Scan links
