Also re-pin qunitjs (follows-up d476e5b955a70). I had forgotten why it was pinned. The reason wasn't for testing convenience (which npm run test-versions covers already), but it was because this was the last version without any npm dependencies and thus avoids pulling in outdated dependencies or npm audit warnings at install time.
Besides, qunit 2.x is already covered by the 'qunit' package so this doesn't need to be updated.
