Summary of Changes

Hello @avik-pal, 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 refactors the continuous integration process for documentation builds within Buildkite. It specifically removes the CPU-based documentation tutorial builds from Buildkite, as indicated by the title's intention to migrate them to GitHub Actions. Concurrently, it establishes a new, dedicated Buildkite pipeline for CUDA-based documentation tutorials, leading to a more modular and streamlined CI setup.

Highlights

• Documentation CI Refactoring: The Buildkite CI configuration for documentation builds has been restructured for better organization.
• CPU Build Relocation: Dedicated CPU tutorial build steps have been removed from the Buildkite pipeline, aligning with the intent to migrate them to default GitHub Actions.
• CUDA Build Isolation: A new Buildkite configuration file, .buildkite/cuda_tutorials.yml, has been introduced to exclusively manage the CUDA documentation tutorial builds.
• Main Pipeline Simplification: The primary Buildkite pipeline (.buildkite/pipeline.yml) has been updated to remove references to the old documentation build process, streamlining its definition.

Code Review

This pull request refactors the documentation build process, intending to move CPU-based builds to GitHub Actions. It removes the comprehensive Buildkite documentation pipeline and introduces a new cuda_tutorials.yml file. However, these changes effectively disable all documentation builds on Buildkite since the triggers in pipeline.yml are removed and the new file is not used. My review highlights a critical FIXME in the new file that forces a draft build and must be removed before merging. I have also noted some latent issues in a commented-out build step that could cause future failures.
