Summary:
Pull Request resolved: https://github.com/facebook/react-native/pull/42899
Updates the `test-e2e-local` script to bootstrap `/tmp/RNTestProject/` using the currently checked out repository as the source of truth for all monorepo packages (previously we only did this for the `react-native` package).
This enables release testers to validate a release **before** physically publishing new dependency versions via `yarn bump-all-updated-packages`.
We are able to reuse the `scripts/template/initialize.js` script that is currently used for E2E validation in CI. This sets up a local Verdaccio server during project install.
NOTE: The time taken for `Build packages` + Verdaccio isn't ideal, I may explore a way to reuse the published package state in a future diff. Until then, this extra time (~1 min) will still be much less pain than the `bump-all-updated-packages` + commit process loop.
