Ghost: Update command not working with .tgz file from build

Issue Summary

Issue Summary

Created a custom zip/tgz file with yarn build and tried to upgrade a docker install of ghost(5.17.1) to it (5.17.2) with ghost update --zip .../../ to the custom one. I’m thinking the package.json has wrong parameters https://github.com/TryGhost/Ghost/issues/15523. When I run the update command as node user in docker after copying the archive I get the output as seen in the log section. Please let me know where the problem lies so I can fix it.

Steps to Reproduce

1. Run Ghost as Docker and `docker exec -it <Container> bash` into it.
   

2. From there go to `/var/lib/ghost` and examine the directories
   

3. As you can see the directory structure is not nearly identical to the new 5. Versions
   

4. Create a zip/tgz with yarn build on your local 5.17.2 instance and copy it to the docker
   

5. Run `ghost update --zip .../../` inside the docker as node user and watch the log
   

6. As you can see, the update command is terminating with the log shown below.
