Subject: [PATCH] Add Nightly support for prebuilds (#49991)

Summary:
Pull Request resolved: https://github.com/facebook/react-native/pull/49991

This change adds nightly support for prebuilds.

t works the same way hermes works: if the react native version contains nightly, we try to use that version to download the right tarball.

To work, it needs to use the `RCT_USE_RN_DEP` env variable.

## Changelog
[Internal] - Add Nightly support to consume ReactNativeDependencies
