This PR adds `convert-to-inferred` generators to convert React Native an
Expo apps using executors to use the corresponding inference plugins.
Also:
1. Fixes casing for `@nx/react-native/plugin` so it is correctly set as
`upgradeTargetName` not `upgradeTargetname`
2. Migration for the above fix for existing projects
We forgot to rename these in the init generator descriptions. This
affects tutorials since we've been including the terminal output with
the wrong scope.
