handling secrets prevents external doc contributions

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 modifies the continuous integration (CI) setup for building documentation. The primary goal is to shift the execution of documentation tutorials from GPU (CUDA) runners to CPU runners. This change is crucial for enabling external contributions to the documentation, as the previous setup involving secrets on GPU runners posed a barrier. By standardizing on CPU runners, the project aims to streamline the contribution process and foster broader community engagement.

Highlights

• Documentation CI Configuration: Updated the device specification for numerous tutorials from "CUDA" to "CPU" to ensure they run on CPU runners.
• Environment Variable Adjustment: Changed the JULIA_CUDA_HARD_MEMORY_LIMIT environment variable to JULIA_CPU_HARD_MEMORY_LIMIT to align with the switch to CPU-based documentation builds.

Code Review

This pull request updates the documentation build process to run all tutorials on CPU runners, which is a great change to facilitate external contributions. The changes to switch from 'CUDA' to 'CPU' devices and update the memory limit environment variable are correct. I've added a suggestion to improve the code formatting for the tutorial lists, which will enhance readability, especially since automatic formatting is disabled for this file.
