Automate the check for the Release on NPM (#49164)

Summary:
One of the steps we perform when doing a release is to run `npm view react-native` to verify that the release has been published and it is available with the right tag.
As of today, we check this manually.

This change aims at automating this check so that we don't have to do it manually ourselves.

## Changelog:
[Internal] - Releases: automate the npm view check

Pull Request resolved: https://github.com/facebook/react-native/pull/49164

Test Plan:
Created a veriftyReleaseOnNPM-tests.js jest test to verify that the script works fine.
