PR is failing because 2.3.7 and magento/module-wishlist-sample-data have dependency conflict. This is happening because we don't have older versions of magento/module-wishlist-sample-data in [mage-os mirror](https://mirror.mage-os.org/) Here's the log for it: https://github.com/graycoreio/mage2docker/runs/7680790648?check_suite_focus=true#step:9:3809
