Summary of Changes

Hello @holtskinner, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request systematically removes all references and support for Python 3.8 across the project. This includes updating continuous integration configurations, project metadata, and documentation to reflect Python 3.9 as the new minimum supported version. The changes streamline the development environment by focusing on currently maintained Python versions, ensuring compatibility and reducing maintenance overhead.

Highlights

Python 3.8 Support Removal: The project has officially dropped support for Python 3.8, aligning with its end-of-life cycle. The minimum supported Python version is now 3.9.
CI/CD Configuration Updates: All Kokoro configurations and GitHub branch protection rules related to Python 3.6, 3.7, and 3.8 have been removed or updated to reflect the new Python version support, including the addition of Python 3.13 and 3.14 for testing.
Documentation and Project Metadata Alignment: The CONTRIBUTING.rst, README.rst, noxfile.py, owlbot.py, and setup.py files have been updated to reflect the change in supported Python versions, including updates to python_requires and programming language classifiers.
Cleanup of Testing Artifacts: The testing/constraints-3.8.txt file, which was specific to Python 3.8, has been removed.

Code Review

This pull request aims to remove support for Python 3.8. While most of the changes correctly reflect this, there are a couple of critical issues in the repository settings that weaken branch protection by removing required CI checks for several Python versions. I've also pointed out a minor cleanup opportunity in one of the noxfiles for better maintainability. Please review the suggested changes to ensure CI coverage remains strong.

Due to some issues with Python 3.9 and associated dependencies, we no longer have it in our python-multi image used by Kokoro. We rely on GitHub Actions to perform the 3.9-unit and system tests. I will suggest some edits to account for that.

📢 Migration Notice: 📢 This library is moving to the google-cloud-python monorepo soon.

We kept this PR open due to recent activity. We would like to finalize this PR so it can be merged if it is critical.

If we don't hear from the PR author, we will close this PR in the next few days. The PR can then be re-opened in the monorepo once the migration is complete and work can continue there.
