Update to current version of babel (7) to get rid of warnings during `npm install`

[strr]

Reason for change

This gets rid of the warnings during npm install about using an old version of core-js such as: """ core-js@<3.23.3 is no longer maintained and not recommended for usage due to the number of issues. Because of the V8 engine whims, feature detection in old core-js versions could cause a slowdown up to 100x even if nothing is polyfilled. Some versions have web compatibility issues. Please, upgrade your dependencies to the actual version of core-js. """

Description of change

Switch to the new babel package names and reference the replacement plugin name in .babelrc

Steps to Test

I ran npm run test before and after and all the tests passed.
