Changes

• [Improvement] Add a weekly GitHub Actions workflow to automatically open PRs when pinned Docker image dependencies (Caddy, MySQL, MongoDB, Redis) fall behind their latest patch release, and a Dependabot configuration to keep GitHub Actions, Dockerfiles, and Python requirements up to date. (by @Danyal-Faheem)

• [Bugfix] Pin the build-time setuptools used inside the isolated PEP 517 build environments that uv/pip create when building Python packages from source. Previously the latest setuptools was fetched to build every sdist regardless of the version installed in the venv, which made builds non-reproducible and broke them when setuptools 81 removed pkg_resources (e.g. when building loremipsum, a transitive dependency of edx-ora2). The constraint is set via UV_BUILD_CONSTRAINT/PIP_CONSTRAINT in the base image stage, so it applies to all requirement installs (base.txt, assets.txt, development.txt, extra requirements and editable installs).

• [Feature] Upgrade OPENEDX_COMMON_VERSION to release/ulmo.4 (by @ahmed-arb)
