Tweak .github/workflows/release.yml

Generate more helpers: 'script.php', 'run.php' and 'run.sh'

If want to open up a generated-project in an IDE (eg for debugging), then it
helps for the project to have some references for running the original script.

Before: Generated project-dir contains *only* downloaded dependencies
After: Generated project-dir contains downloaded dependencies as well as:

- A symlink to the script ('script.php')
- A helper to run the script ('run.php' or 'run.sh')
