Adding a common module in turborepo

A lot of times you need a module that can be shared by both frontend and backend apps

Initialize a packages/common module

cd packages
mkdir common

Initialize an empty node.js project

npm init -y
npx tsc --init

Change the name to @repo/common
Export a few things from src/index.ts

export const NUMBER = 1;

Add it to the package.json of various apps (next app/react app/node app)

"@repo/common": "*",

Import it in there and try to use it
Run npm install in root folder and see if it works as expected
