CI ARM

[johnnynunez]

This pull request includes significant updates to the .github/workflows/ubuntu-openblas.yml file, focusing on updating the Docker build and test processes, as well as removing unnecessary steps related to the ARM64 job.

Key changes include:

Docker Build and Test Updates:

• Updated the Docker build and test scripts to use openblas-amd64-py312-dev instead of openblas-amd64-py310-dev.

ARM64 Job Simplification:

• Removed the skip-arm64-check-on-fork job and its associated steps, simplifying the workflow.
• Changed the runs-on parameter for the openblas-arm64 job to use ubuntu-24.04-arm instead of ubuntu-latest.
• Removed the complex steps for creating and managing a VM for the ARM64 job, replacing them with Docker build and test steps similar to the AMD64 job.

Hi @johnnynunez please take a look at the ARM64 CI errors. You can ignore the Windows CI errors, they are unrelated.

Any status on this? We'd really like ARM64 wheels so that we can move past Open3D 0.18.

Thanks.

I do this in my free time, error still not detected
