Added the deployment status event for waiting on GHA deployment

[ethriel3695]

Support the deployment_status event type for Github Actions.

This allows consumers to support running Playwright or Cypress tests after a deployment is complete to a third party platform such as Vercel when using the action in the same workflow file.

Fixes #647

Example Configuration

The following configuration currently exits with an error for unsupported event type. This PR fixes the error.

The Fork won't run our CI jobs so I created an identical PR.
