Code Review

This pull request updates the README for the a4-highgpu-8g example. The changes include updating command examples to use full paths, moving the 'Additional ways to provision' section, and adding a new 'Clean Up' section. My review identifies a couple of areas for improvement in the new documentation to enhance clarity and correctness. The instructions for alternative provisioning methods are slightly ambiguous, and the new 'Clean Up' section incorrectly refers to a 'GKE cluster' and uses an inconsistent placeholder for the deployment name. Addressing these points will make the documentation more accurate and easier for users to follow.
