**Is your feature request related to a problem? Please describe.**
As of the time of this issue, the Graph Notebook project has a build workflow that creates and publishes a container image in the AWS ECR Public Gallery with only a AMD64 supported architecture. This image can only be used on ARM-based machines (Apple M1/M2, Amazon Graviton, etc.) via the use of emulation, which can have stability issues.

**Describe the solution you'd like**
The request here is to change the build/publish workflow to create a multi-architecture image that supports both AMD64 and ARM64 architectures.
