security vulnerability in serialise-javascript in < v3.1.0 used by copy-webpack-plugin v5.1.0

[Aaditya-Sahay]

The package serialise-javascript has seen a new security advisory, which requires libraries using it to update to a version beyond v3.1.0.
You can find the advisory here: GHSA-hxcc-f52p-wc94

react-styleguidist depends upon copy-webpack-plugin versions ^5.1.0, which in turn depends upon an older version of serialise-javascript, namely v2.12.0.
This can be fixed by changing the version of copy-webpack-plugin from ^5.1.0 to any of the latest versions, ideally ^6.0.3

It would be great to get this updated as its throwing off some warnings in a few places.

Happy to file a PR if needed.
