Code Review
This pull request updates the bigframes library to version 2.40.0, including version bumps across configuration files and the addition of release notes. It also toggles release_only_mode to false in the librarian configuration. Feedback was provided regarding the inclusion of unrelated Babel-related entries in the CHANGELOG.md that should be removed to maintain relevance.

These changelog entries appear to be unrelated to the bigframes project. They reference Babel (JavaScript) components and link to the babel/babel repository. These should be removed to maintain a clean and relevant changelog for the Python package.
