* feat: 🎸 Expose extension config to modules
Currently, only the preRegistration hook receives the extension's
configuration as a parameter. Providing getModuleFn's with the
extension's configuration, and all lifecycle/modules with the
application's configuration as rootConfig should open the doors to more
configurable extensions.
