setup-gradle v4 + Remove unnecessary Gradle Wrapper Validation (#47389)

Summary:
As per: https://github.com/gradle/actions#the-wrapper-validation-action

> Starting with v4 the setup-gradle action will [perform wrapper validation](https://github.com/gradle/actions/blob/main/docs/setup-gradle.md#gradle-wrapper-validation) on each execution. If you are using setup-gradle in your workflows, it is unlikely that you will need to use the wrapper-validation action.

I'm moving to setup-gradle v4 and remove this unnecessary extra action.
