refactor(mc-scripts): manually group some vendor chunks

[emmenko]

Branched off #2995

Extracted from #2821

To reduce the main bundle chunk even more, we can instruct the bundlers to group certain vendor packages in specific groups. As a result, the main bundle will have a smaller size. Users (via browsers) will then only need to download the smaller main bundle when it gets updated (caching) as the other vendor chunks didn't change (unless via dependency updates).

I found this article that explains well how and why it's useful like that: https://www.codemzy.com/blog/react-bundle-size-webpack-code-splitting
