Correctly declare runtime dependencies (#41398)

Summary:
In pnpm setups, codegen will fail during build because it cannot find its dependencies. Some of the dependencies it relies on at runtime are currently declared under `devDependencies`. This change moves them to `dependencies`.

## Changelog:

[GENERAL] [FIXED] - Fix `react-native/codegen` not being able to resolve dependencies in pnpm setups

Pull Request resolved: https://github.com/facebook/react-native/pull/41398

Test Plan: We are currently trying to [enable pnpm mode](https://github.com/microsoft/rnx-kit/pull/2811) in rnx-kit and hit this issue. We've patched this package locally and it works.
