Subject: [PATCH] fix(autoupdate): make Go major updates real

A Go major update changes the import path. Without rewriting imports the
PR only added the new module to go.mod, the tests passed, and Renovate
proposed it again. Rewrite the imports with gomodUpdateImportPaths so the
build tests the actual update, and cap indirect dependencies at their
current major, which the parent module decides.
