Suggestion: Webpack migration guide

[benjamingr]

It would be useful to have a guide explaining how to migrate from Webpack 4/5 to esbuild. In particular an example taking a real Webpack config file and building the code with esbuild would be useful:

• Migrating from webpack.IgnorePlugins
• Migrating from webpack.DefinePlugin (setting process.env.FOO = someValue)
• How to migrate code using base64-inline-loader
• Migrating alias
• Migrating noParse clauses
• What to do with currently used additional loaders (like ng-annotate-loader)
• Migrating from webpack.HtmlWebpackPlugin
• Migrating from webpack.FaviconsWebpackPlugin
• Migrating from webpack.BannerPlugin
