function createConfig(configSetters) {
  return core.createConfig({ webpack, webpackVersion }, [createEmptyConfig].concat(configSetters))
}
Takes an array of webpack blocks and creates a webpack config out of them.
Each webpack block is a callback function which will be invoked to return a
partial webpack config. These partial configs are merged to create the
final, complete webpack config that will be returned.

Wraps @webpack-blocks/core's `createConfig`.

@param {Function[]} configSetters  Array of functions as returned by webpack blocks.
@return {object}                   Webpack config object.
