Support TypeScript in split-platform-components

[rickdunkin]

Currently only .js files are recognized by the split-platform-components rule. This update should allow for TypeScript support as well.

@Intellicode can this be merged? At the moment we are having to switch it off manually

overrides: [
    {
      files: ["*.ios.ts", "*.ios.tsx", "*.android.ts", "*.android.tsx"],
      rules: {
        "react-native/split-platform-components": 0,
      },
    },
  ],

@rickdunkin, @omonk sorry for the delay, thanks for the contribution! I'll make a release shortly
