This repo is a template repo and the README.md says to use the "Use this template" button.
But this won't copy the commit history, so no references to the .env file exists in the student repo.
Right now, because of that, the grading will pass without any interaction from the student since there is already no commits referencing the .env file in their repo.
This repo should not be configured as a template and the documentation should be updated to use a fork instead. Or add instructions so they create their own .env commits.
