App hosting portion of code lab not correct

### [REQUIRED] Project setup

### [REQUIRED] Describe the problem

I run npm init @apphosting and it scaffolds all the necessary files to deploy to app hosting when using angular ssr. The code lab gives an angular example and deploys but theres no explaining how to deploy the ssr version which is given by App hosting Get Started tutorial linked within the code lab.
