addAliases(aliases) {
        webpackConfig.addAliases(aliases);

        return this;
    }
Allow you to add aliases that will be used by
Webpack when trying to resolve modules.

See https://webpack.js.org/configuration/resolve/#resolve-alias

For example:

```
Encore.addAliases({
    Utilities: path.resolve(__dirname, 'src/utilities/'),
    Templates: path.resolve(__dirname, 'src/templates/')
})
```

@param {Record<string, string>} aliases
@returns {Encore}
