Use explicit package list and ensure it is tested in CI (#232)

* In `pyproject.toml`, use an explicit package list instead of using the
`find` directive.

* In GitHub Actions workflow, do not use an editable install since that
implicitly includes all modules below `uncertainties/` and we want to
make sure we test the package in its installed form.
