fix: pin vike version to 0.4.236 in vue-ssr testapp (#3500)

## Summary

Vue SSR e2e tests fail in CI because the testapp's `npm install --force`
resolves `vike@^0.4.193` to the latest 0.4.x, which is broken:

- **0.4.237** has a build error (`Cannot read properties of undefined
(reading 'client')`)
- **0.4.238+** requires vite 6, but the testapp uses vite 5

This pins vike to **0.4.236** — the latest version that works with vite
5.

## Test plan

- [ ] Vue SSR e2e tests pass in CI (both dev and prod)
