added example usage of set datastructure by avinashkrishna613 · Pull Request #2534 · redis/node-redis

Description

I faced some difficulties while working on sets and later found the value for set should be string. So i just add the example for how to use set datastructure in a node application.

@avinashkrishna613 I made some more changes, I think it's ready.. wanna review my changes please? 🙏
