bug: test suite won't run if we don't use hatch envs

Right now hatch environments are a default. But if we don't use them, then the ci for tests as written i don't think will run We need to test the template when we don't use hatch envs (in the custom mode) and double-check that CI and other things work. https://github.com/pyOpenSci/pyos-package-template/blob/main/template/%7B%25%20if%20use_git%20and%20dev_platform%20%3D%3D%20'GitHub'%20%25%7D.github%7B%25%20endif%20%25%7D/workflows/test.yml.jinja I could be wrong but that is just what i see in the template as is right now.
