feat(crnl): pass --template blank to create-expo-app

[atlj]

Summary

With Expo SDK 51, Expo has changed their default app template. This PR passes the --template blank param to create-expo-app so we can use a bare template. This also fixes some of the CI issues we've been having

Test plan

1. Create a new library and select Javascript as the library language
2. Make sure the generated library's example/package.json doesn't include expo-router as a dependency (expo-router is a dependency that comes with the new default app template).
3. Run yarn lint and make sure it passes.
