313 - Release design system npm package version 1.1.0

[MellyGray]

What this PR does / why we need it:

This PR updates the package.json of the design system with the new version 1.1.0. @iqss/dataverse-design-system

Also I added some instructions to the README on how to publish a new version.

A part from that I added a preset to lerna so the CHANGELOG.md is automatically updated with the new commits since the last version. See Conventional Commits for commit guidelines.

Which issue(s) this PR closes:

• Closes Release design system npm package version 1.2.0 #313

Special notes for your reviewer:

The automation of the publishing will be developed in this other issue:

• Automate the publication of the @iqss/dataverse-design-system package #140

The creation of a test registry will be developed in this other issue:

• Create test registry for the @iqss/dataverse-design-system package #144

Suggestions on how to test this:

To test the package:

1. Create a new React application. I'll go with the first option which is running npx create-next-app in your machine (ensure you have node installed in your machine)
2. In your app root folder run npm i to install all the packages of the demo app
3. Follow the instructions from the README of the package @iqss/dataverse-design-system
4. If you're using npx create-next-app then go to the src/app/page.tsx file
5. Place the imports at the top of the file with the other imports import { Col, Container, Form, Row} from "@iqss/dataverse-design-system";. If you are using next-js you'll need to set 'use client' at the top of the file since the design system components are client components
6. Now copy the example code in the usage section of the package README and paste it somewhere inside the Home function of the src/app/page.tsx file
7. Run the application using npm run dev and go to http://localhost:3000 to see the application using the design system components
