ci(test-vp-create): scope remote-vite-react-ts matrix to pnpm

The newly added `remote-vite-react-ts` matrix entry passes on pnpm but
fails on npm/yarn/bun with ERR_PNPM_NO_MATCHING_VERSION for
@voidzero-dev/vite-plus-core@0.0.0 — even in the (npm) job.

Root cause: create-vite@9.0.5 writes `"packageManager": "pnpm@..."`
into the scaffolded package.json, which `vp install` follows over the
`--package-manager` CLI flag. Combined with the local-tarball
overrides CI uses (which are written in a form pnpm-standalone won't
consult on the second install), install #2 falls back to the npm
registry for vite-plus-core@0.0.0 and fails.

Wiring --package-manager through remote-template scaffolds (and
updating the overrides injection to match) is separate infrastructure
work. For now, exclude npm/yarn/bun combinations via a matrix
`exclude` so the regression coverage we gain on pnpm is still in CI
without red builds on the other three.
