Code Review

This pull request is an automated release PR to bump the version of google-api-core to 2.29.0. The changes include updating the version in version.py and .librarian/state.yaml, and adding a new entry to CHANGELOG.md. My review focuses on the correctness of the generated changelog. I've found that the links in the new changelog entry are incorrect and inconsistent with previous entries, and I've provided a suggestion to fix them.

[gemini-code-assist]

The links in this changelog entry appear to be incorrect. They point to the google-cloud-python repository instead of python-api-core. Additionally, the format of the links is inconsistent with previous entries:

• The version comparison link incorrectly prefixes tags with google-api-core-.
• The commit SHAs in the link text are full-length instead of the conventional short format.

For consistency and correctness, please update the links.
