fix: install @types/node so you do not need to add types > node in …

[joshstevens19]

…tsconfig.json

Description

When you use the typings on a ts project which isnt a node project you have to manually go into your tsconfig > types and add node. Importing node types itself in the dependencies of the packages which use them will solve that.
