started the slack bot project!

i added the code in from the guide that allows the bot to reply when someone uses a command, but currently you can use it only if im running the code for it.

i like that ive learned how to run some commands inside the terminal, since i had rarely done that before.

it was a bit confusing installing the necessary things required for it like node and nest, but i figured it out, and my nest application was approved, so i will work on getting this slack bot running 24/7!
