Update website apps to use GitHub action for Deploy

[elrayle]

Description

The website and dev-website Azure are currently deployed using Azure pipeline. This issue proposes moving deploy to a GitHub action that builds the docker image, publishes it to GitHub packages, and deploys the app to Azure. This reduces barriers for outside adopters who may want to deploy to an architecture other than Azure apps.
