Allow action to be used without Gradle invocation
If the user supplies no 'arguments' parameter, the action will function as a
'setup-gradle' action, adding Gradle to the PATH and enabling other features
without actually running a Gradle build.

Any subsequent Gradle invocations in the workflow will benefit from:
- Save/restore of Gradle User Home
- Save/restore of configuration-cache data
- Capture of build-scan URLs

These features are enabled via Gradle User Home, so any Gradle invocation that
uses the same Gradle User Home will be included.
