ci: mark unforked monorepo packages as private (#2483)

## Summary:

It's not clear (both to humans and to build tools like `nx`) that the
only packages we fork from the React Native monorepo upstream are `
'react-native' --> 'react-native-macos'` and
`'@react-native/virtualized-lists' -->
'@react-native-mac/virtualized-lists'`. The rest of the packages should
essentially only ever be used in local development, while the published
package `react-native-macos` uses the upstream versions of these
packages. We can solve this by marking the packages as private.

## Test Plan:

IIRC, this caused some build failure last time I tried this.. let's see
how CI reacts to this change. Further testing with `nx release` should
be done locally to make sure the nx build graph stops marking the
unforked monoreppo packages as dependencies.
