Migrate Webpack to use Asset Modules

[catarak]

How would this new feature help increase access to the p5.js Editor?

Add stability to the p5.js Editor by keeping packages up to date

Feature enhancement details:

I just upgraded to Webpack v5, but I did not upgrade to Asset Modules. raw-loader/url-loader/file-loader are going to be deprecated in the next version, so it would be good to update this.
