Deploy Script to generate the backend cache

[nozomione]

Context

Related issue: #208

As with the existing refine.bio, we want to generate the backend cache in the project folder on pre-build which can be used by several components (e.g., about, footer).

Problem or idea

Implement a pre-build script to synchronously generate the backend cache in JSON format and write them out to a file (currently named as apiData.js) in the project folder.

Solution or next step

• Implement a deploy script for the backend cache
• Use it in the required components
