Linux/arm64 Building Image Support

[romer8]

Describe the solution you'd like
Addition of amd64 in the image built of the Tethys Platform

Problem Statement
Currently, the Tethys Platform Docker image lacks support for the amd64 architecture. This creates compatibility issues when deploying applications that rely on a multi-platform architecture, such as tethys-ngiab, which is designed to run on both arm64 and amd64 platforms. Without amd64 support, the application fails to start in environments where amd64 architecture is required.

Proposed Solution
Support for amd64 architecture in the official Tethys Platform Docker image. This can be done by enabling multi-platform builds (both arm64 and amd64) during the image creation process. By including amd64, the platform will be more flexible and allow applications like tethys-ngiab to run smoothly on a wider range of hardware.

Additional context
The app called tethys-ngiab for visualization of outputs of the Nextgen model is build for multiplatform architecture (arm64 and amd64), and it will fail to start if the parent image in this case (the Tethys platform image) does not have support for multiplatform built
