chore: add repository directory for all packages.json (aws#17203)

> If the package.json for your package is not in the root directory (for example if it is part of a monorepo), you can specify the directory in which it lives:
> ```json
> "repository": {
>   "type" : "git",
>   "url" : "https://github.com/facebook/react.git",
>   "directory": "packages/react-dom"
> }
> ```
> — https://docs.npmjs.com/cli/v6/configuring-npm/package-json#repository

I use a lot https://njt.vercel.app/ to jump to different packages information,
and with this PR we can know exactly what package in what folder lives

Made the changes with a script to make it easier 🙂
