Add npm version in engines in package.json

          The error log shared in the original description mentions that there is a conflict of dependencies.

A simple way to resolve this temporarily is to use the attribute --forceor --legacy-peer-depsalong with npm install The final command will look like: npm install --force/ npm install --legacy-peer-deps

Engineers are expected to install peer dependencies manually, this change was introduced in v3.x, and has been updated in v7.x of npm.

You may use the temporary solution for now, till I raise a PR to start using v7.x and above.
