[OTHER] Update README.md file to include clean installing dependencies

[at-the-vr]

What would you like to share?

During process of local setup for the forked repo, users tend to miss installing the dependencies involved (prettier) in this case. This can cause indentation/line feed based errors in future.
Possible Solution: asking users to run npm ci in their forked repo can resolve such issues.

Do I want to work on this Issue: No

Ok I was most certainly under impression that users can fork + clone instead of using their Browsers to create the json file (that's on me). In that case I would like to know if this issue can be avoided by the Users since I cant think of a solution for this one
