BONUS TODO: Display complete movie details for a given movie ID
Open this link in your browser (and check Pretty-print checkbox) to view json format:

INSTRUCTIONS:
1. Call getMovieById(movieId) to get the JSON response string
2. Check if response is null (if yes, print error and return)
3. Parse the JSON string to JsonObject (inside try-catch)
4. Use Gson to extract all fields from the JSON and map them to your Movie class:
- Add missing JSON fields to your Movie class first (actors, awards, director,
imdb_id, imdb_votes, metascore, plot, rated, released, runtime, type, writer)
- Then use Gson to parse your json string
5. Print all movie details in a readable format
(PUT ALL PARSING CODE INSIDE THE EXISTING try-catch)
