Export @react-native/typescript-config/strict shorthand

[kraenhansen]

Summary:

Extending a tsconfig seems simpler than adding compilerOptions with customConditions.

Before

{
  "extends": "@react-native/typescript-config",
  "compilerOptions": {
    // ...
    "customConditions": ["react-native-strict-api", "react-native"]
  }
}

After

{
  "extends": "@react-native/typescript-config/strict"
  // ...
}

Changelog:

[GENERAL] [ADDED] - Add @react-native/typescript-config/strict export enabling the react-native-strict-api custom condition.

Test Plan:
