Details

Hi, in micro-frontend guides here https://modernjs.dev/en/guides/topic-detail/micro-frontend/c02-development.html
We can see

 runtime: {
    router: true,
    state: true,
    masterApp: true,
  },

but accepted types for masterApp is RuntimeUserConfig.masterApp?: Config | undefined

Options:
1 Changing guides to reflect new changes
2 Extend accepted types to prevent this inconsistency

I can create a PR with a fixed one once we agree what is the best option.
