refactor: Remove python-dateutil dependency (#2529)

* Remove upper limit of 2.8.0 for python-dateutil. * Drop python-dateutil dependency * Re-add dateutil to ATTRIBUTION since it is in the build-image (dependency of dependency) * Run make update-reproducible-reqs now we are no longer directly depending on python-dateutil Co-authored-by: Mathieu Grandis <73313235+mgrandis@users.noreply.github.com> Co-authored-by: _sam <3804518+aahung@users.noreply.github.com>
