fix(e2e): normalize reusable workflow reference to @main

Replace the branch-based reference with @main for the plugin-e2e
reusable workflow. The @main branch of .github is protected and
already contains all necessary pnpm support. This removes the drift
risk from referencing a non-protected branch.
