[.github] - feature: add manual workflow dispatch for deploying infra…

…structure

 - Introduce workflow_dispatch trigger with a configurable input for deploying to the 'us-central1' region
 - Implement concurrency control to manage deployment processes and prevent collisions
 - Authenticate with Google Cloud and set up the Cloud SDK for deployment tasks
 - Build a Docker image using Cloud Build and a custom script, with parameters for image name and Dockerfile path
 - Generate a GitHub App token dynamically for use in the workflow
 - Enable triggering of a downstream repository's workflow using a repository dispatch event with a custom payload including the region and image tag
