As part of #69, we encountered that there are quite some input variables, which are not passed into the Docker container. https://github.com/extdn/github-actions-m2/blob/4091e3ae8e47b4fdaa049a9c64a088c1d06d02f1/magento-integration-tests/entrypoint.sh uses the following inputs, which are not passed into the Docker container here:

• INPUT_ELASTICSEARCH
• INPUT_PHPUNIT_FILE
• INPUT_COMPOSER_VERSION
• INPUT_REPOSITORY_URL
• INPUT_PRE_PROJECT_SCRIPT
• INPUT_POST_PROJECT_SCRIPT
• INPUT_MAGENTO_PRE_INSTALL_SCRIPT
• INPUT_MAGENTO_POST_INSTALL_SCRIPT

Wouldn't all these variables need to be passed as well? Am I missing something?
