Adds a Hydrogen v2 template which is the output of the `npm create @shopify/hydrogen@latest` command.
Note that a `vercel.json` file is being used to define the environment variables that are required at runtime. This is required for the template to deploy with zero configuration, however the user should update these values (including replacing the session secret) and migrate them to the Project settings in the Vercel dashboard.
[Live example](https://hydrogen-v2-template.vercel.app)
These tests will run if one of the conditions is met:
- any change to `./examples`
- any changes to `./packages/frameworks`
The test ensures that examples can build and deploy without errors.
In a future PR, we could improve these tests to make requests to the
test deployment (like we do for probes).
