* Process jQuery UI source files.
*
* Each file being processed creates 3 files under assets/vendor/jquery.ui/:
* - The original source for audit purposes, with a `.js` suffix.
* - The minified version for production use, with a `-min.js` suffix.
* - The source map for debugging purposes, with a `-min.js.map` suffix.
*
* @param {object} data
* Object passed to the callback.
* @param {object} data.file
* Normalized file information object.
* @param {string} data.file.from
* Path of the file in node_modules/ directory.
* @param {string} data.file.to
* Path of the file in core assets/vendor/ directory.
* @param {string} data.contents
* Content of the file being processed.
*
* @return {Promise<[{filename: string, contents: string}]>}
* Return a Promise that resolves into an array of file and content to create
* in the assets/vendor/ directory.
