Add support for `react-native.config.ts`

[szymonrybczak]

Describe the Feature

It would be nice to support TypeScript version in react-native.config, I have no idea if there are any tools that have hardcoded path to react-native.config.js, so I have no idea if that would be a potential breaking change.
