Fix use of yarn pack

[mimarz]

We currently have a folder called node_modules in our dist for when a package is built. This folder contains the version of our packages used internally which is needed for components in our library.

We have hit an unfortunate snag where yarn pack ignores any folder named node_modules when packing, making its tarballs broken.

Investigate the following options:

• Figure out if we can overwrite this ignore feature in yarn pack.
• Maybe rename the built node_modules folder to something else?
• If yarn pack cant be fixed. Remove the script pack:react in our root

I have been investigating this, and it seems like it is meant to ignore any folders with the name node_modules.
As can be seen here.

It was mentioned in this yarnpkg/yarn#2063 and then again in yarnpkg/yarn#5966, which should have a merged a fix for it, but the fix with bundledDependencies does not seem to work today.

As @mimarz mentioned, we should probably remove yarn pack:react. npm pack will contain node_modules, so I suggest using that.

@mimarz I think we can pick this back up now that we have Yarn 4. @Albertlarsen maybe you could take a look, since you did the update?

Suggest we remove the pack:react which uses yarn pack and call it a day.
