 * @summary Removes the "use strict" directive from all JavaScript files in a specified directory.
 * The motive here is that the chess script breaks when webpack automatically compiles it in.
 *
 * @requires fs
 * @requires glob
 *
 * @constant {string} distDir - The directory containing the bundle files.
 * @constant {RegExp} useStrictRegex - The regular expression to match the "use strict" directive.
 *
 * @function removeUseStrict
 * @returns {void}
