Starting with the `v3` release, this action will delegate to `gradle/actions/setup-gradle`.
All repository sources have been migrated to https://github.com/gradle/actions, and
are no longer required in this repository.
Workflows testing the action functionality have been retained, but any workflows involving
building or inspecting code have also been migrated to `gradle/actions`.
- Translate to env var for init-script support
- Use when deciding whether to log or rethrow errors
- Add a custom error type to trigger failure in post action
