Update test/CNA templates React version to 19.2.0 (#84736)

The peerDeps are already bumped to 19.2.0 at
https://github.com/vercel/next.js/pull/84463, but the test/CNA templates
weren't updated as the `syncPagesRouterReact` value is always false at
the moment, which blocked the update.

Therefore, remove the `syncPagesRouterReact` condition to match the
actual peerDeps bump.
