Show code comments in union types

Suggestion

When I use union types in Typescript, the annotations of the types are missing and cannot be given. I would like to be able to show some code its meaning with the help of annotation hints.

✅ Viability Checklist

My suggestion meets these guidelines:

• This wouldn't be a breaking change in existing TypeScript/JavaScript code
• This wouldn't change the runtime behavior of existing JavaScript code
• This could be implemented without emitting different JS based on the types of the expressions
• This isn't a runtime feature (e.g. library functionality, non-ECMAScript syntax with JavaScript output, new syntax sugar for JS, etc.)
• This feature would agree with the rest of TypeScript's Design Goals.

💻 Use Cases

Comienza con el ejemplo enlazado de TypeScript Playground y revisa cómo se representan las anotaciones de tipo unión mostradas. Aclara la sintaxis de comentarios esperada, el alcance de las herramientas afectadas y los casos de uso antes de identificar las ubicaciones de implementación y de pruebas. Se considera terminado cuando las anotaciones de los miembros de la unión se pueden escribir y mostrar sin cambiar el JavaScript emitido.
