GitHub action: provide deploy script

[de-jcup]

Situation

There are many steps necessary to deploy the github action

• npm install
• npm run build
• npm test
• manual check only index.js has been changed
  • if others, deployment is (potentially) not okay
  • if index.js is missing it is not a deployment
  • means may only be index.js
• add all (means only index.js) to stage
• commit with deployment info
• push to remote repo

Wanted

An easy way to automate this.

Solution

Provide a ./deploy.sh script which does automate this.
