chore: add testing on arm64 architecture using qemu (#95)

## Description

Add arm64 architecture and qemu for running the tests. This allows us to
test and publish arm64 packages even if they still need to contain some
amd64 images.

 This package is designed for use as part of a [UDS Software Factory](https://github.com/defenseunicorns/uds-software-factory) bundle deployed on [UDS Core](https://github.com/defenseunicorns/uds-core).
 
+> [!IMPORTANT]  
+> The `arm64` package includes `amd64` images due to lack of availability of `arm64` images from upstream projects at this time. This means you can deploy the `arm64` package on an `arm64` kubernetes cluster, but some of the images contained in the package will require emulation (e.g., qemu or rosetta) to run properly.

 > [!TIP]
 > To add additional environment variables to Mattermost you can do so by overriding the `extraEnv` key in the `uds-mattermost-config` chart.
