Summary of Changes

Hello @loosebazooka, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request focuses on optimizing the Cloud Build environment by enhancing its computational resources and updating its core build tool. The changes involve provisioning a more powerful machine type for build execution and refreshing the Bazel builder image to its latest version, aiming to improve build performance and leverage recent toolchain improvements.

Highlights

• Cloud Build Machine Type Upgrade: The machine type used for Cloud Build jobs has been upgraded from 'N1_HIGHCPU_8' to 'E2_HIGHCPU_32', providing significantly more CPU resources for builds.
• Bazel Builder Image Update: The SHA256 digest for the 'gcr.io/cloud-builders/bazel' image has been updated, ensuring the build process uses a more recent version of the Bazel builder.

Code Review

This pull request updates the Cloud Build configuration, increasing the machine size and upgrading the Bazel builder image. My review focuses on improving the maintainability of this configuration. I've suggested adding comments to document the significant increase in machine resources and its justification, as well as to specify the new Bazel version, which is a major upgrade. These additions will provide important context for future developers regarding build performance, cost, and dependencies.
