feat: add -i alias for --interactive option

[szymonrybczak]

Summary:

-i is easier and faster to type.

Test Plan:

1. Clone the repository and do all the required steps from the Contributing guide
2. Run this command:

node /path/to/react-native-cli/packages/cli/build/bin.js run-ios -i

3. Should work the same as with --interactive

Checklist

• Documentation is up to date to reflect these changes.
• Follows commit message convention described in CONTRIBUTING.md
