Use npm install --legacy-peer-deps (#326)

Fixes #309 Unfortunately a lot of React.js apps have this problem with peer deps because older dependencies specify pre-v19. Because Dyad app templates do (and should) explicitly specify React as a dependnecy, using `--legacy-peer-deps` gives us the right behavior where it effectively does not install peer deps and avoids the React version errors. For pnpm, we have an explicit lockfiles for our templates so there isn't an issue.
