Proposed changes

This fixes the issue with missing tests.

Updates the workflow to use prefer-source instaed of prefer-dist.

Some modules recently added a .gitattributes which specifies ignoring tests dir when prefer-dist is used, so they were not being run. This looks like it was updated in moduls only in the past month or so, so as the PHP scaffolding PRs merged they were slowly being lost... This should fix it though!
