Rollup merge of rust-lang#134368 - ehuss:edition-links, r=jieyouxu
Use links to edition guide for edition migrations This switches the migration lints for the 2024 edition to point to the edition guide documentation instead of the tracking issues. I expect the documentation should be easier to understand for a user, compared to most of the issues which don't have any direct information, and can be a bit confusing to navigate, or have outdated information.
