Project: Hangman - Fix the cause of confusion

[atulvishw240]

Because

Earlier the text was giving this wrong idea that there's a way to save the whole class state using Serialization. While in reality you can only save the state of particular objects. I spent a considerable amount of time on various Subreddits and Stackoverflow to find a way to serialize my whole game class, only to learn it that I can't.

This PR

I removed the extra bit "you can serialize your game class too", which caused the confusion for me and many others.
