Update Documentation

• Added example pr and repo to the readme
• added color and icon to the action yml
• added a CONTRIBUTING doc for repo guidelines

First stable

First stable version that includes functionality:

• Set workspace folder eg. /packages/
  • Allows for subfolders eg. /packages/components/{scope}
• Add a prefix to the label eg. pkg: or scope:

Then will automatically label pull requests with package scope

For example if I have a folder structure of

packages/
    core/
        core.js
    tools/
        tools.js

And I make a code change to core.js the PR will be labelled with pkg: core
