Update Gradle Action, create unit tests

Updated the Gradle build action to use 'gradle/actions/setup-gradle' rather than the deprecated 'gradle/gradle-build-action'

Updated documentation for Actions workflow for Gradle Wrapper Validation

Added unit testing, this will run tests on the robot if there are early signs of errors with the robot software.
