test(migrate): regenerate @vitest/* catalog snaps and add varlet #10 regression

Part 2 flips declared @vitest/* providers and coverage packages from concrete
pins to `catalog:` (with the catalog gaining the entries); regenerate the
migration global snaps that shift so the CI diff check passes. Add a unit
regression for the varlet #10 shape: a catalog using legacy vite-plus-test
wrapper aliases keeps its `catalog:` refs while the catalog entries are
rewritten to upstream.
