This workflow prevents the links that are broken or 404 errors by
checking the documentation links during development and before merging
into the main code base. This ensures all project documentation (Readme
, contribution files) remains current and functional , proactively
addressing technical debt. Please note this is a resubmission of a
previous [PR](https://github.com/googleapis/genai-toolbox/pull/1756)
that was closed due to merge conflicts
