/**
 * Inspired by: https://github.com/webpack/webpack/issues/8115#issuecomment-663902035.
 *
 * This plugin modifies the webpack bootstrap code generated by the plugin at
 * webpack/lib/web/JsonpMainTemplatePlugin.js and the CSS chunk loading code generated
 * by @automattic/mini-css-extract-plugin-with-rtl.
 *
 * It will rename the function jsonpScriptSrc generated by that to webpackJsonpScriptSrc
 * and install a new version that checks a user provided variable containing a script
 * version parameter to specify in async chunk URLs.
 *
 * The jsonpScriptSrc override is only for webpack 4 (tested with 4.43 and 4.44).
 *
 * Webpack 5 has official support for this https://github.com/webpack/webpack/pull/8462
 * so it won't be necessary.
 *
 * It will also append the ?ver parameter to CSS chunk hrefs loaded by @automattic/mini-css-extract-plugin-with-rtl.
