+- [Bugfix] On the main branch, bump the pinned build-time `setuptools` to 80.9.0 (the release branch keeps 69.1.1). The older version cannot build packages that declare their license with the PEP 639 `project.license` field (e.g. `mysqlclient`) against the Open edX master branch, which broke `tutor images build openedx` on main.
