**Is your feature request related to a problem? Please describe.**
As of the time of this issue, the Graph Explorer 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.

**Additional context**
N/A

Locate the container image build and publish workflow for the AWS ECR Public Gallery, then inspect how it currently targets AMD64. Update the workflow so the published image supports both AMD64 and ARM64, and verify that both architectures can pull and use the resulting image.
