Code Review

This pull request automates the release of version 2.29.0. The changes correctly update the version in the project files and add the corresponding changelog entry. My review identifies an issue with incorrect URLs in the generated CHANGELOG.md file, where links point to the wrong repository. This should be corrected to ensure documentation accuracy.

[gemini-code-assist]

The generated link for the version comparison points to the google-cloud-python repository and uses an incorrect tag format. It should point to python-api-core and use the vX.Y.Z tag format to be consistent with previous entries. All other links in this new section for version 2.29.0 have a similar issue with the repository.
