test(e2e): Type-check the react-router-7-router-entry app

The v7 router-entry app only ran Playwright and its tsconfig used
`moduleResolution: "node"`, which ignores the package `exports` map and so
cannot resolve the `@sentry/react/router` subpath types - meaning it never
type-checked the new API, unlike the v6/v8 apps. Switch it to
`moduleResolution: "bundler"` and run `tsc --noEmit` in `test:assert`, matching
the other two. Verified locally that all three (v6/v7/v8) type-check against
their respective React Router major.
