Next.js SSR with Contentstack Live preview

How to use

1. Create one entry with title and single_line field.
2. create next.config.js using the next.config.sample.js
3. Run the project within Contentstack

What have we done

The idea is to use the SSR documentation for the live preview. We moved the ContentstackLivePreview.init() at the utils.js where we have initialized the Contentstack. Then, we have used the Stack.livePreviewQuery and passed the query param to it. We got the query param from the prop of getServerSideProps().
