Add a bash script that inserts/updates <link rel="canonical"> tags in all Javadoc HTML files across all versions, pointing to the latest stable version. This points search engines to use the latest stable versions of the API docs and consolidates SEO ranking signals. When a Javadoc page doesn't exist in the latest version (e.g., a removed API), the script points the canonical URL to the newest version that still contains the page, instead of pointing to a 404. Also update README.md to document the new step in the release process.
Run add-javadoc-canonical-urls.sh to add <link rel="canonical"> tags across all existing Javadoc HTML files in static/*/javadoc/. Pages that exist in the latest version (42) get a canonical pointing there. Pages for removed APIs point to the newest version that still contains them.
