Code Review

This pull request updates the Cloud Build configuration for ML A4X HighGPU Slurm tests by adding logic to inject a guest_accelerator block into the blueprint. The feedback suggests consolidating the multiple sed commands into a single, more robust command to improve maintainability and prevent accidental matches on generic strings elsewhere in the file.
