bump all github actions to use @v2/v3 syntax #37

	# This workflow uses actions that are not certified by GitHub.
	# They are provided by a third-party and are governed by
	# separate terms of service, privacy policy, and support
	# documentation.
	# This workflow will build a Java project with Gradle and cache/restore any dependencies to improve the workflow execution time
	# For more information see: https://help.github.com/actions/language-and-framework-guides/building-and-testing-java-with-gradle
