change the example of Mario and princes in chapter 3

[lhy1025a]

Details(细节)

Your tutorials are great and your contribution to web3 is respectable. But in Chapter 3, you use an example of Mario and the princess, which is very disrespectful to women and makes female readers feel very uncomfortable. You will lose a lot of female readers because of this example. It would make this project even better if we could change the example to another like a chef and a steak.
