The publish tool should not be overwriting previously published packages.

Overwriting published packages is against npm's policy, and I'm not sure how this was even possible because the npm registry should be immutable.

We are using @types/react-redux 7.1.16. That npm package was originally published 9 months ago, but overwritten 6 days ago.
https://www.npmjs.com/package/@types/react-redux/v/7.1.16

I started looking into some of the other packages that would have been affected by that same PR.
https://www.npmjs.com/package/@types/chai-enzyme/v/0.6.7
https://www.npmjs.com/package/@types/emoji-mart/v/3.0.4
https://www.npmjs.com/package/@types/enzyme/v/3.10.8

All @types packages affected by the above PR have their previously published npm packages overwritten 6 days ago.
