Update favicons-webpack-plugin dependency

[peacememories]

Currently I am not able to use elm-pages on macos with node 13, because the version of favicons-webpack-plugin it depends on in turn depends on sharp v0.22.1. The first version supporting node 13 is v0.23.2, which is depended on by the current version of favicons-webpack-plugin, so a dependency update should fix this.

Hey, thanks for the suggestion and context. I looked at this a while back but it wasn't out yet, or there was something blocking it. I had to use a beta version to get version 4 of the html-webpack-plugin, but it seems to work fine. Here's the commit: 31f23a5. And here's the changelog entry.

Let me know how it goes with using this with Node 13!

Thanks for the quick fix! The install now runs without a problem.
