Support for ARM64 Docker Images

[romga]

Currently, Databricks only provides Docker images for x86_64 (AMD64) architectures. With the increasing adoption of ARM64-based cloud instances (such as AWS Graviton) and ARM-based development environments (like Apple Silicon Macs), it would be beneficial for Databricks to provide official ARM64 Docker images.

Here is the change that allow building images for ARM64 (like Apple Silicon Macs)

E.g. to get databricksruntime/python:15.4-LTS built for Mac

• clone the repo
• checkout release-15.4-LTS branch
• apply the patch
• in ubuntu/minimal docker build -t databricksruntime/minimal:15.4-LTS .
• in ubuntu/python docker build -t databricksruntime/python:15.4-LTS .

Would also love to see this get pushed up to mainstream. We have started to build our own images to support our developers workflow and would much prefer a static base to pull from

I would also like to see this merged in as well. It is not just for developer convenience, but can also be a significant cost savings on larger workloads.

Hi - @xinzhao-db / @justindu-db I see that you two are the most recently active maintainers on this repository. Are you guys the right people to tag, or is there a better point of contact about getting this issue prioritized?
