Code Review

This pull request updates the versions and changelogs for several Google Cloud Python libraries, including the onboarding of google-cloud-appoptimize and google-cloud-iamconnectorcredentials. Key changes include feature additions for bigquery-magics, google-apps-chat, and google-cloud-dlp, along with bug fixes for google-api-core, google-auth, and google-cloud-spanner. Feedback was provided to correct a truncated bug fix description in the google-cloud-spanner changelog.

[gemini-code-assist]

The bug fix description appears to be truncated with an ellipsis (p…). Based on the referenced PR #16561, the full description should be "catch recursion and decode errors in proto parsing to python".

Suggested change

	* catch recursion and decode errors in proto parsing to p… (#16561) ([70dc6bfc328de37abe96afbf5555e484fdc80058](https://github.com/googleapis/google-cloud-python/commit/70dc6bfc328de37abe96afbf5555e484fdc80058))
