[.github] - infra: new connectors deploy workflow (#8661)

* [.github] - feature: add manual workflow dispatch for deploying infrastructure

 - 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

* [.github] - fix: update secrets and app ID for connector infra deployment

 - Switch to using specific app ID and private key for infra deployment
 - Correct the environment variable used for the GitHub token in the dispatch event trigger

* [.github] - fix: correct working directory path in GitHub Actions config

 - Ensure the `cloud-build.sh` script uses the correct relative working directory by adding a leading `./` to the path configuration

* [.github] - fix: use secret for INFRA_DISPATCH_APP_ID in GitHub Actions

 - Changed the GitHub App ID reference to use secrets for enhanced security and better management of sensitive data
 - This update ensures that the App ID is not exposed in the workflow file, aligning with best practices for credential storage
