docs(upgrade): move the M:N read note to the 0.13→0.14 cycle

0.13.0 shipped without the sql-orm-client M:N runtime, so the note
describing the correlated include reads belongs in the 0.13→0.14
extension-author instructions, not the now-released 0.12→0.13 doc. The
upgrade-coverage gate targets 0.13→0.14 after the release bump.
