Upgrade copy-webpack-plugin for the webpack-config npm package

[spoilerdo]

When I ran npm i on an empty expo typescript template I got one moderate vulnerability:

Currently I use version: 0.12.11 of the @expo/webpack-config npm package. Maybe better to update this in the package itself. copy-webpack-plugin current version is 6.0.1 (which uses version 3.0.0 of serialize-javascript) and the webpack-config package uses 5.0.0.

Hi @spoilerdo, thanks for bringing this up! It's kind of unfortunate that the advisories are popping up in places where it shouldn't. The advisory clearly states that it's only a moderate risk when using outside Node, and this is used in Node 😅 But that's a topic for another discussion I think.

Any help upgrading this is appreciated, if you can feel free to open a PR. If not, don't worry, we will get to this eventually. Let's keep this on our todo list for now.

Thanks!
