NPM warning on core-js 2.6.11

[dnedrow]

(NPM version 6.14.3)

When installing github-release-notes, npm generates the following warning:

npm WARN deprecated [email protected]: core-js@<3 is no longer maintained and not recommended for usage due to the number of issues. Please, upgrade your dependencies to the actual version of core-js@3.

> [email protected] postinstall /Volumes/Development/kiwidocs/node_modules/core-js
> node -e "try{require('./postinstall')}catch(e){}"

Thank you for using core-js ( https://github.com/zloirock/core-js ) for polyfilling JavaScript standard library!

So it appears that something needs updated to core-js 3 or better. I'm not sure if it is github-release-notes itself, or a dependency.

I'll add more once I've had a chance to probe further.
