fix(cli): fix yarn install failure in vp create

Two issues caused yarn install to fail in CI for newly created projects:

1. In CI (CI=true), yarn Berry defaults to enableImmutableInstalls which
   prevents creating a new lockfile. Pass --no-frozen-lockfile to
   vp install since vp create always needs to generate a fresh lockfile.

2. Standalone yarn projects had no .yarnrc.yml created during migration.
   Without nodeLinker: node-modules, yarn 4 defaults to PnP which
   doesn't work with vite-plus. Now rewriteYarnrcYml() ensures
   nodeLinker is set and is called for standalone projects too.

Also removes all yarn exclusions from the create e2e test workflow
(full 12-job matrix now enabled).
