[Feature Request] Add GitHub action to implement a CI for the shortcode

[anvithks]

Is your feature request related to a problem? Please describe.
Currently there is no CI in place to test whether the changes made to the shortcode work in the real world.
Any change needs to be installed on a demo site manually and checked in the CI for the demo website
Demo site Source code is here

Describe the solution you'd like
When new code is added to the shortcode the CI should take the code from the PR, spawn the website code with the latest shortcode and check for any build errors and show a deploy preview. This is implemented in the Demo site using the netlify integration.

Describe alternatives you've considered
Currently no alternatives considered. Open to suggestions and any PRs that can implement a solution for this.
