## Which issue does this PR close? - Closes #20572 ## Rationale for this change When upgrade guides were split into separate pages (#20183), the old `upgrading.html` URL broke. All changelog files still reference this old URL, causing 404 errors for users. ## What changes are included in this PR? Added a redirect in `docs/source/conf.py` using the existing `sphinx_reredirects` extension to redirect `library-user-guide/upgrading.html` to `library-user-guide/upgrading/index.html`. This preserves all existing changelog links without needing to update historical files. ## Are these changes tested? Tested locally - the redirect works correctly, including with anchor links (e.g., `upgrading.html#datafusion-46-0-0`). ## Are there any user-facing changes? Yes - users clicking old changelog links will now be redirected to the correct page instead of getting a 404.
