Re-create .env file in test jobs after workspace extraction

- Add steps in run_php_74_unit_tests and run_php_80_unit_tests to ensure $HOME/tooling/docker-unit-tests/.env exists after workspace extraction.
- Export ENV_FILE to point to the .env file before running the docker unit tests.
- This guarantees that the script's source command has a valid filename, fixing the "No such file or directory" error.
